The post-processing utility <tt>postProcessWaves2Foam</tt> can be used to analyse various kinds of probes data. The utility can read data extracted from a simulation both as runTime and as a post-processing step from the following data times:
 
 
* The surfaceElevation (using the native <tt>waves2Foam</tt> utility)
 
* The forces (using the native <tt>OpenFoam</tt> utility <tt>forces</tt>)
 
* The velocities in points (using the native <tt>OpenFoam</tt> utility <tt>probes</tt>)
 
* The overtopping flux (using the native <tt>waves2Foam</tt> utility)
 
 
Furthermore, the utility can perform the following types of analysis on the data sets:
 
 
* Evalutation of powerSpectra (FFT and least squares methods)
 
* Decomposition into reflected and incident wave components (FFT and least squares methods)
 
 
Other miscellaneous methods are described below.
 
 
==== Basic Layout of Input File ====
 
All the control is defined in the file <tt>constant/postProcessingProperties</tt>. As a global choice, the following entry is needed:
 
deleteParentOutputDirectory false;
 
This option deletes the output directory (<tt>postProcessedWaves2Foam</tt>) used for all the post-processing.
 
 
It can contain any number of sub-dictionaries of the following example (description of each method is described below):
 
interpData
 
{
 
    // Folder name for the output in <tt>postProcessesWaves2Foam</tt>
 
    callName interp;
 
 
    // A wordList of actions to be performed in the user defined order
 
    actionList ( removeSubDirs interpolateSurfaceElevation powerSpectraFFT write2Ascii );
 
 
    // The indices of the data sets used in the analyses "powerSpectraFFT" and "reflectionAnalysis2DFFT"
 
    allDataSets yes;
 
 
    // Specs for the interpolation of the raw data sets.
 
    // Equidistant data sets are needed for some of the post-processing methods
 
    deltaT 0.25;
 
    tMin  1033.0;
 
    tMax  3600;
 
     
 
    // Spectral windowing details - used by FFT-methods
 
    freqBins 1024;
 
    windowShiftFraction 0.5;
 
}
 
One potentially important feature is that a given operation do not need to begin with reading of the raw data. One could e.g. add the following sub-dictionary to work on the same interpolated data set:
 
interpDataCont
 
{
 
    // Note that the operation know works on the same read data
 
    callName interp;
 
     
 
    // A wordList of actions to be performed in the user defined order
 
    actionList ( reflectionAnalysis2DFFT removeData);
 
 
    // The indices of the data sets used in the analyses "powerSpectraFFT" and "reflectionAnalysis2DFFT"
 
    indices 3(4 5 6);
 
   
 
    // Spectral windowing details - used by FFT-methods
 
    freqBins 1024;
 
    windowShiftFraction 0.5;
 
 
    // Physical properties needed for the reflection analysis
 
    // The depth is for computation of linear wave number and coordName is the
 
    // direction of the reflection analysis. Currently, an arbitrary direction is not supported,
 
    // however, it does not seem so important in the case of 2D reflection analysis.
 
    depth 50;
 
    coordName x;
 
 
    // Removal of outputted data in the <callName> directory
 
    removeOF false;    // Default value = true;
 
    removeAscii false; // Default value = false;
 
}
 
The benefit of having two dictionaries is that the reflection analysis works on very specific sets of data, so a specific list of indices must be stated for the analysis to make sense. The computation of the power spectra on the other hand, can easily be performed on all of the data sets in one go.
 
 
==== Reading and Writing of Raw Data ====
 
Four method is available, and they are all capable of reading from a set of time folders, so in case of a restart of the simulation, the probes data can be concatenated:
 
inputDir <inputDirName>; // Depending of input data, this option has a default value
 
timeDirs ("0" "10.34");  // This is not required. Default is all time directories
 
===== rawSurfaceElevation =====
 
This method reads the surface elevation. The option <tt>inputDir</tt> has a default value of <tt>surfaceElevation</tt>.
 
 
===== rawVelocityProbes =====
 
This method reads the velocities probes in runTime. The option <tt>inputDir</tt> has a default value of <tt>probes<tt>.
 
 
===== rawAlphaProbes =====
 
This method reads the alpha1 probes in runTime. The option <tt>inputDir</tt> has a default value of <tt>probes<tt>.
 
 
===== rawOvertopping =====
 
This methods reads the overtopping flux. The option <tt>inputDir</tt> has a default value of <tt>overtopping</tt>.
 
 
Furthermore, the method has an additional option called <tt>overtoppingScaling</tt>, which has a default value of 1.0. This is used to scale the overtopping flux from m3/s to m3/s/m, which is needed in e.g. 2-dimensional simulations, where the width of the domain differs from 1.0 m.
 
 
===== rawForcesAndMoments =====
 
This method reads the forces and moment extracted using the forces-<tt>functionObject</tt>. The option <tt>inputDir</tt> has no default value, and only the values for one patch is read per <tt>inputDir</tt>.
 
 
==== Reading and Writing of Interpolated Data ====
 
The writing of interpolated data is based on the input method in the raw-data methods, hence those inputs for those described above is also required, when interpolating the data.
 
 
Furthermore, the following input is required by the user
 
deltaT <scalar>; // The equidistant time step for the interpolation
 
tMin  <scalar>; // Not required. Default = the smallest logged time instance
 
tMax  <scalar>; // Not required. Default = the largest logged time instance
 
 
The reading of forces and moments outputs two data files, where the forces are outputted with index 0 and moments are outputted with index 1.
 
 
The available methods are the following:
 
* interpolateSurfaceElevation
 
* interpolateVelocityProbes
 
* interpolatedAlphaProbes
 
* interpolateOvertopping
 
* interpolateForcesAndMoments
 
 
==== Naming of Main Data ====
 
The data read (and written) using the raw and interpolated methods is outputted using the naming scheme
 
postProcessedWaves2Foam/<callName>/<callName>_<index>
 
Here, <tt>index</tt> runs from 0 to N-1, with N being the number of data sets.
 
 
==== Other IO Data Manipulation ====
 
===== write2Ascii =====
 
If <tt>write2Ascii</tt> is put in the action list, then data outputted from any of the <tt>raw*</tt> or <tt>interpolate*</tt> are outputted in ASCII format with none of the header OF-header files.
 
 
The OF-formatted filename is followed by the string <tt>.txt</tt>, when outputted.
 
 
No options.
 
 
==== Choice of Indices ====
 
Several of the methods below acts on data sets, which do not necessarily include all of the data sets. Therefore, it should be possible only to target a sub-set of the indices, so the choice on indices are as follows:
 
allDataSets no; // Default value = false / no
 
indices 6( 1 3 4 5 6 7);
 
If <tt>allDataSets</tt> is set to <tt>yes</tt>, then the input <tt>indices</tt> is ignored.
 
 
==== Ensemble Averaing ====
 
The method <tt>ensembleAverage</tt> performs an ensemble average of the data set. The following options are needed
 
period <scalar>; // The return period
 
The output is an ensemble average with a time step of <tt>deltaT</tt>, however, this is not a needed option, because it comes from the interpolation routine, also if an interpolation method is not in the action list.
 
 
This method is only valid, if <tt>period / deltaT</tt> is an integer.
 
 
Data is outputted in <tt>postProcessedWaves2Foam/<callName>/ensembleAverage</tt>
 
==== Spectral Methods ====
 
 
 
 
 
===== Output =====
 
Data is outputted in <tt>postProcessedWaves2Foam/<callName>/<spectralMethod></tt>
 
 
==== Cleaning Methods ====
 
===== removeData =====
 
If <tt>removeData</tt> is put in the action list, then files of the type <tt>Foam::fileName::FILE</tt> are removed in the directory <tt>postProcessedWaves2Foam/<callName>/</tt>.
 
 
Options:
 
removeOF false;    // Default value = true. Removes data files with OF format.
 
                                            E.g. as written by rawSurfaceElevation or interpolateSurfaceElevation;
 
removeAscii false; // Default value = false. Removes data files of ASCII format as written by write2Ascii.
 
 
 
===== removeSubDirs =====
 
If <tt>removeSubDirs</tt> is put in the action list, then all the directories in <tt>postProcessedWaves2Foam/<callName>/</tt> are removed.
 
 
No options.

Revision as of 17:39, 17 August 2017

The library waves2Foam is a toolbox used to generate and absorb free surface water waves. Currently the method applies the relaxation zone technique (active sponge layers) and a large range of wave theories are supported and the relaxation zones can take arbitrary shapes.

Release of the waves2Foam Manual

As of the 17th of August 2017, the waves2Foam Manual is released. Consequently, the content of this Wiki-page is reduced.

It is still possible to find download/installation instructions and information on the code contributions.

1 waves2Foam - Information

1.1 Report Bugs via the Mantis on Sourceforge

Please report bugs (not compilation errors, unless they are bugs) here:

https://sourceforge.net/apps/mantisbt/openfoam-extend

There is a subsection for waves2Foam. This will make it easier to keep track of issues, which needs attention.

1.2 Discussions on cfd-online.com

There are two main threads on cfd-online.com, which are related to waves2Foam.

For announcements please consider [1]. Note that questions will generally not be answered here. It is a source of communication on development/release topics. For enquiries, discussion, etc., please use [2].

2 Utilities

2.1 Pre-processing

2.1.1 faceSetToSTL

A simple program, which can be used to create simple STL-surfaces. The user defines a closed cell with an arbitrary number of faces or defines one face and an extrude direction. Based on this an STL-file is written.

The program relies on the face triangulation inside OpenFoam.

In the input dictionary, and arbitrary number of STL-definitions can be specified.

2.1.2 waveGaugesNProbes

This utilities allows for simple creation of a set of wave gauges. Several types are distributions are available, and the output is

  • A set file, which contains all of the wave gauges
  • A code snippet, which can be copy-pasted into the controlDict, such that runTime sampling is activated. This code snippet comes with some default settings, which the user should consider
  • A surfaceElevationDict, such that sampling of the free surface can be done as a post-processing step
  • A VTK-file, such that it is easy to visualise the location of the wave-gauges in e.g. ParaView.

The the input dictionary, several sets of wave gauges can be defined. This is interesting, if e.g. five specific gauges are used for reflection analysis, and the other e.g. 100 gauges are for dense measuring. This split makes the post-processing of the reflection analysis faster and less error-prone.

This utility is prepared for the creation of probe location files as well, however, this is work to be carried out.

2.1.3 setWaveParameters

This utility runs through every sub-dictionary (SD) in the dictionary waveProperties.input. A pointer to a derived class of setWaveProperties is generated for each SD; the pointer is based on the entry waveType. If the necessary input is available, the additional wave parameters are computed.

The derived data and the other needed input are written to the file waveProperties, which is subsequently used in the simulations.

As of revision 1982 the utility has become independent on the mesh, so unnecessary time for loading the computational mesh is avoided. This loading could potentially take a long time and on really big meshes prevent the execution on a serial machine.

2.1.4 relaxationZoneLayout

A tool for visualising the relaxation fields in the computational domain. It also depicts the orientation of the relaxation zone. A tutorial is availabel.

2.1.5 setWaveField

This utility sets the initial condition in the computational domain. The entry initializationName in waveProperties defines which sub-dictionary is used for initialising the wave field.

NB! Note that the ramp-up factor is multiplied onto the expressions also during initialization of the computational domain. Hence, in order not to get a horizontal water surface and stagnant water, the parameter Tsoft should be given a value of 0.0; Tsoft is typically set to the wave period as default and is not required by most of the wave theories.

2.2 Post / Run-Time Data Extraction

2.2.1 surfaceElevation

This utility is a specialisation of the OpenFoam/src/sampling/sampledSet/sampledSets in such a way that the sampled (scalar) quantity is integrated along a line defined in the file surfaceElevationDict. The utility is intended to by used as a post-processing utility, where the void ratio field is integrated along a vertical line, which yields the location of the free surface.

Since it is a specialisation of the native sample-utility, it runs both in serial and parallel modes. The two calls are as

surfaceElevation [-latestTime] [-time ranges]
mpirun -np NPROCS surfaceElevation -parallel [-latestTime] [-time ranges]
2.2.1.1 Input File

An example of the input file is placed in applications/utilities/postProcessing/surfaceElevation. The rules are the same as for sampleDict, however, it only makes sense to sample the void ratio field, e.g. gamma or alpha1.

The utility only considers scalar fields.

2.2.1.2 Output File

The output file is placed in surfaceElevation/startTime/surfaceElevation.dat, and it contains all the sampled data for all sampled time steps. The formatting is as follows:

Time lineName0 lineName1 lineName2 // Merely some string references
-1   x0        x1        x2        // The x-coordinates of the first point on the sampling line. -1 has no meaning.
-2   y0        y1        y2        // The y-coordinates of the first point on the sampling line. -2 has no meaning. 
-3   z0        z1        z2        // The y-coordinates of the first point on the sampling line. -3 has no meaning.
0.0  eta0      eta1      eta2      // The elevation for Time = 0.0 s
0.1  eta0      eta1      eta2      // The elevation for Time = 0.1 s
0.2  eta0      eta1      eta2      // The elevation for Time = 0.2 s
0.3  eta0      eta1      eta2      // The elevation for Time = 0.3 s
0.4  eta0      eta1      eta2      // The elevation for Time = 0.4 s
0.5  eta0      eta1      eta2      // The elevation for Time = 0.5 s
2.2.1.3 Why -1e15 ?

The value -1e15 is written to the output file under the following circumstances:

  • The number of points along the integration line is less than 2.
  • Both the top and the bottom integration points are either 0 or 1 within a tolerance of 0.0001. -1e15 is preferred as this suggests the integration line to be fully inside or outside of the water column.
2.2.1.4 Used as FunctionObject

The utility can also be used as a functionObject. The tutorial waveFlume includes an example on how to use it.

In this mode a couple of additional time controls has been implemented into surfaceElevation. These are

samplingStartTime <scalar>; // Default value: 0.0

This stalls the sampling of the interface location until the specified starting time is exceeded.

surfaceSampleDeltaT <scalar>; // Default value: -1.0

This value only has an effect, if it is strictly larger than 0.0. It modifies the output time for the sampling, so it is not control by neither a constant number of time steps nor the global output time. This allows for a sub-time step output of the surface elevation and thus saves disk space. This delta time does not feed back into the global setting of the time step, thus the output is only at intervals of approximately surfaceSampleDeltaT, where the accuracy obviously increases with decreasing deltaT / surfaceSampleDeltaT. So forth this ratio exceeds 1, one or more outputs is simply omitted.

For optimal uses of the surfaceSampleDeltaT, it is also recommended to specify the following

outputControl timeStep;
outputInterval 1;
2.2.1.5 Compatibility

This utility has been tested for compatibility with OF-1.6, OF-1.7, OF-2.0 and OF-2.1.

The utility does not compile with OF-1.5.

3 waveProperties File

The file: waveProperties is to be placed in constant and must contain the following:

seaLevel 0.0; // Defines the still water level
wind (0.0 0.0 0.0); // Defines the velocity in the air part. Not needed. Default value:= vector::zero.
relaxationNames ( <word0> <word1> ); // The list of names of the relaxation zones used in the simulation
initializationName <wordN>; // Used by setWaveField and it is the sub-dictionary, 
                            // which defines which wave theory to be used for initialization
pName <word>;

Furthermore, sub-dictionaries are needed for every boundary, which uses any of the boundary conditions:

waveAlphaFvPatchScalarField    (type: waveAlpha)
wavePressureFvPatchScalarField (type: wavePressure)
waveVelocityFvPatchVectorField (type: waveVelocity)

and for all of the relaxationNames and the initializationName. The name of the sub-dictionaries are e.g.

<word0>+Coeffs

Please note that if an boundary called inlet uses one or several of the boundary conditions, then it is allowed for instance to have a relaxation zone called inlet in order not to duplicate the input.

An example of a combined boundary and relaxation zone input is given here, where Stokes first order wave theory (Airy wave) is the input

inletCoeffs
{
   // Wave type to be used at boundary "inlet" and in relaxation zone "inlet"
   waveType    stokesFirst;  
    
   // Ramp time of 2 s
   // Foam::sin(2 * mathematicalConstant::pi / (4.0 * Tsoft_) * Foam::min(Tsoft_, runTime.time().value() ))
   // and explicitly "1" for Tsoft = 0
   Tsoft       2;

   // Water depth at the boundary and in the relaxation zone
   depth       0.400000;

   // Period - needed by setWaveParameters -> yields omega
   period      2.0;

   // Cyclic wave frequency
   omega       3.141593;

   // Phase shift in the wave
   phi         0.000000;

   // Wave propagation direction - needed by setWaveParameters -> yields k with period and depth
   direction   (1 0 0);

   // Wave number vector, k. 
   waveNumber  (1.70048 0.0 0.0);

   // Wave height
   height      0.1;
    
   // Specifications on the relaxation zone shape and relaxation scheme
   relaxationZone
   {
       relaxationScheme Spatial;
       relaxationShape  Rectangular;
       beachType        Empty;
   
       startX           (0 0.0 -1);
       endX             (5 0.0  1);
       orientation      (1.0 0.0 0.0);

       // Additional optional arguments
       relaxationWeight Exponential; //Default and otherwise: FreePolynomial, ThirdOrderPolynomial
       courantCorrection off; // Default and otherwise: on
   }
};

4.2 Use of relaxationZoneLayout

4.2.1 Relaxation Zone Layout

  • Name: tutorials/relaxationZoneLayout
  • Utility: relaxationZoneLayout
  • Description: This tutorial will show how to use the utility to obtain a visual on the relaxation zones. This could be helpful to detect potential problems in the setup.

4.3 Use of waveFoam

4.3.1 Wave Flume

  • Name: tutorials/waveFoam/waveFlume
  • Solver: waveFoam
  • Description: This tutorial will show the user how to use the constant/waveProperties dictionary to set-up the wave properties, relaxation zones and initialization specifications.

4.3.2 Standing Wave

  • Name: tutorials/waveFoam/standingWave
  • Solver: waveFoam
  • Description: This tutorial shows how to handle wave generation and a fully reflecting sea wall utilising the relaxation zone technique.

4.3.3 3D Wave Flume with a Seawall

An example of the surface elevation with waves from 3 directions onto a vertical structure.
  • Name: tutorials/waveFoam/3Dwaves
  • Solver: waveFoam
  • Description: This tutorial shows the use of relaxation zones in 3 dimensions. There are 3 inlet relaxation zones and one outlet relaxation zone. In the middle of the wave tank there is a vertical internal wall on which the waves are reflected. The waves, which are generated in the 3 inlet relaxation zones, have different directions relative to the x-axis.

NB: Some reflection does occur on the wall perpendicular to the wave outlet.

4.3.4 Periodic Solitary

  • Name: tutorials/waveFoam/periodicSolitary
  • Solver: waveFoam
  • Description: This tutorial uses the method for initialising a wave profile, which is different from a flat water surface with a sea-level, which differs from 0 m. The computational domain is cyclic in the direction of wave propagation and the initial field is a solitary wave.

NB: In the simulation a portion of the wave propagates in the opposite direction of the actual wave propagation. It is considered to be due to the fact that the solitary wave theory does not fulfil the non-linear wave problem accurately enough, which is why a part of the wave energy is reflected on the wave itself. It has been tested to initialise with and without the analytical expression for the excess pressure, however, it does not make a difference. Experimental evidence of this behaviour is reported in [1].

4.3.5 Square Pile in Cylindrical Domain

The surface elevation around a square pile in a constant and unidirectional current. The gray area is the relaxation zone.
  • Name: tutorials/waveFoam/squarePile
  • Solver: waveFoam
  • Description: This tutorial shows how to use the cylindrical relaxation zone. A unidirectional current is the target function all the way around, hence one relaxation zone acts as both generation and absorption. The relaxation zone removes the internally generated surface disturbances. It could be interesting to have it tested for ships waves. Alternatively, a better shape for that purpose, e.g. an elliptical relaxation zone shape could be implemented.

NB: Generating waves in the computational domain in this tutorial will give bad results. This is a direct consequence of the huge variation in cells per wave length depending on the location in the domain and not the relaxation method! Particular attention should be given to circular domains with waves.

4.3.6 Wave Transformation over Submerged Bar

  • Name: tutorials/waveFoam/bejiBattjes
  • Solver: waveFoam
  • Description: This tutorial provides the experimental setup from [2] and a Matlab script, which can be used to compare the experimental data and the simulations.

5 Development / On-going and Future

  • In connection with each of the wave theories in src/waveTheories/, there should be a corresponding file in src/setWaveProperties/, which computes all of the necessary properties based on a minimum number of inputs, e.g. have height, H, water depth, h, and wave period, T.
This work is still ongoing, hence for those waves missing a property-file, the pre-processing tool setWaveParameters will fail.
  • Tests with other outlet boundary types [3][4]
  • The pressure gradient points in the direction of the boundary face, irrespectively of the fact that it should be corrected for the angle between wave propagation and the direction of the boundary face.
  • The pressure gradient is not implemented in all of the wave theories - returns instead \partial p/\partial n = 0.0.

6 Download and Installation

6.1 Dependencies

Besides the standard dependencies in OpenFoam, waves2Foam also depend on Gnu Scientific Library (GSL). This is needed for two reasons:

  • In the cnoidal wave theory one has to evaluate Jacobian elliptic functions and complete elliptic integrals. These are not natively available in OpenFoam.
  • A pre-processing tool, which is currently being developed, computes the needed wave parameters giving the minimal number of input parameters. This quickly results in a set of N non-linear sets of equations in N unknowns. For this purpose GSL is currently being used.

GSL can e.g. be downloaded using the following commands[5]

Ubuntu: sudo apt-get install libgsl0-dev gfortran
Fedora: sudo yum install gsl-devel
Suse:   sudo zypper install gsl-devel

Please be aware that the location for GSL might differ between OS's, hence the include paths in the options-files could be wrong. If you have successfully installed GSL and the compilation complains over missing header files or libraries, this is the first place to look.

Additional dependencies:

  • gfortran
  • git

6.2 SVN on SourceForge

The toolbox is available through the OpenFoam-Extend SourceForge SVN. Check out the code in the following manner:

svn co http://svn.code.sf.net/p/openfoam-extend/svn/trunk/Breeder_1.6/other/waves2Foam

6.3 Installation

  • Install GSL as described above
  • Obtain the source code via SVN as described above
  • Execute the Allwmake script in the folder waves2Foam
    • The Allwmake script might cast an error in terms of instructions. Merely follow these.
    • Other errors could be a lot of things:)
