IHFOAM is a set of solvers and boundary conditions to generate and absorb water waves actively at the boundaries and to simulate their interaction with porous coastal structures.

The main scope of these modelling tools is coastal, marine, hydraulic and offshore engineering.

1 IHFOAM Overview

The IHFOAM package includes:

• Individual boundary conditions for wave generation and active wave absorption for alpha1 and U fields. (libIHwaveGeneration.so)
  • IH_Waves_InletAlpha
  • IH_Waves_InletVelocity
• Boundary conditions for pure wave absorption applicable to U field. Based on 2D or 3D theories, both are applicable to 3D cases. (libIHwaveAbsorption.so)
  • IH_3D_3DAbsorption_InletVelocity
  • IH_3D_2DAbsorption_InletVelocity
• Solvers to be used with your favourite version of OpenFOAM or FOAM-extend. See compatibility below.
• Brief reference manual
• Tutorials and validation cases

1.1 Supported Versions of OF

Valid versions:

Known issues:

• the boundary conditions compile and work.
  • The regular version of interFoam needs to include "-linterfaceProperties" to compile.
  • IHFOAM solver compiles and works. Although the BCs are included, apparently they are not linked, as they are not recognized.
  • If the boundary conditions are included dynamically in controlDict and used with IHFOAM, turbulence modelling does not work.

• the boundary conditions compile and work.
  • No IHFOAM solver is included, as we are experiencing severe problems with pressure calculations (not linked in any way to IHFOAM implementation) in this version. We are preparing an extensive bug report for the OpenFOAM developers. In the mean time we suggest you stay with prior OpenFOAM versions.
  • Should you want to use wave generation and absorption, see below how to link the boundary conditions dynamically in controlDict.

1.2 Ongoing Development

• The current version is 2.0, as released in 15th July 2014.
• Bug fixes will be issued on a regular basis, while the development of version 3.0 is currently ongoing.
• The new version will include major changes in the structure of the boundary conditions, which will not affect the use.

Future releases will include:

• Volume-averaged turbulence models, as seen in the third paper.
• Current generation (already pre-implemented but not referenced, as it needs further work and validation).
• Wave theories implemented as classes, gathered by an autoPtr.

Future releases may include:

• Custom IHdynamicRefineFvMesh to enable dynamic mesh refinement on snappyHexMesh-generated meshes, as seen in the fourth paper.

2.2 Dynamic linking of the boundary conditions

In order to include the wave generation and active wave absorption boundary conditions without needing to re-compile a solver, write the following code in controlDict:

libs
(
    "libIHwaveGeneration.so"
    "libIHwaveAbsorption.so"
);
