Physical Properties Setup
- Physical properties are stored in directory constant
- Let us look in it:
# ls $FOAM_RUN/icoFoam/cavity/constantpolyMesh transportProperties
- In the directory one can also find computational mesh and one configuration file transportProperties
- There may be numerous files, depending on the solver
- Let us write the file transportProperties as a standard output:
# cat $FOAM_RUN/icoFoam/cavity/constant/transportProperties/*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 2.2.1 | | \\ / A nd | Web: www.OpenFOAM.com | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class dictionary; location "constant"; object transportProperties; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // nu nu [ 0 2 -1 0 0 0 0 ] 0.01; // ************************************************************************* //
- Configuration file transportProperties has only one parameter – kinematic viscosity nu = 0.01

- Reynolds number is:
