2 Synopsis

execFlowFunctionObjects [OPTIONS]

3 Description

Quoting from OpenFOAM's source code [1]:

Executes the set of functionObjects specified in the selected dictionary (which defaults to system/controlDict) for the selected set of times. Alternative dictionaries should be placed in the system/ folder.

The flow (p-U) and optionally turbulence fields are available for the function objects to operate on allowing forces and other related properties to be calculated in addition to cutting planes etc.

-noZero

Exclude the 0 directory from the times list

-time RANGES

Select time steps. RANGES follows the time selection rules

-latestTime

Apply only on the latest time available

-constant

Include the constant directory in the times list

-parallel

Run the utility in parallel

-roots "(DIR1 [...DIRN])"

Directories through which the data are distributed

-region NAME

Specify a mesh region by its NAME

-dict FILE

Read control dictionary from specified location. Note: but it will still use the main system/controlDict for the base runtime options, except the function objects.

-case DIR

Execute the command on the case directory DIR. If not provided, use the current directory

-noFlow

suppress creating flow models

-noFunctionObjects

Skip the execution of the functionObjects - note: this pretty much ruins the usage of this application.

-help

Display the help and exit

4 Tips

• The -noFlow option means that it will load all known fields for each time instance and then run the function objects. But with this option, none of the turbulence models will be loaded.
• The following thread (at CFD-Online) explains how to add the ability to load more fields: execFlowFunctionObjects - unknown field problem
• The following thread (at CFD-Online) explains how to add the ability to add a _loop mode_ to execFlowFunctionObjects: execFlowFunctionObjects (post #4)
• A minimalistic variant of execFlowFunctionObjects for relying solely on function objects is available here: wyldckat@github:execFunctionObjects
• execFlowFunctionObjects can also be used with simpleFunctionObjects
