Hi,
i want to use a nonlinear viscosity model for a specific case like powerlaw or birdcarrue but when i change Newtonian to powerlaw or birdcarreu in transportproperties , the solver run it with the Newtonian model. HTML Code:
/*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM Extend Project: Open Source CFD | | \\ / O peration | Version: 1.6-ext | | \\ / A nd | Web: www.extend-project.de | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class dictionary; object transportProperties; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // transportModel BirdCarreau ; nu nu [0 2 -1 0 0 0 0] 0.01; BirdCarreauCoeffs { nu0 nu0 [ 0 2 -1 0 0 0 0 ] 0.0244370772e-3; nuInf nuInf [ 0 2 -1 0 0 0 0 ] 0.0030515582e-3; k k [ 0 0 1 0 0 0 0 ] 4.9414230738; n n [ 0 0 0 0 0 0 0 ] 0.4635742916; } Thanks |
