Laminar simpelFOAM in Openfoam
Hi all,
I am trying to run a laminar simpleFoam simulation, but the simulation stops after running for the first time step. I get something like this when running the simulation: Timestep 1 <runs simulation> Timestep 2 Simulation STOPS without error I have set the following in the turbulenceProperties file /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: plus | | \\ / A nd | Web: www.OpenFOAM.com | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class dictionary; location "constant"; object turbulenceProperties; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // simulationType laminar; // ************************************************** *********************** // and my controlDict setting are as follows: application simpleFoam; startFrom latestTime; startTime 0; stopAt endTime; endTime 1; deltaT 0.001; writeControl timeStep; writeInterval 1; purgeWrite 0; writeFormat ascii; writePrecision 7; writeCompression off; timeFormat general; timePrecision 6; runTimeModifiable true; adjustTimeStep yes; maxCo 0.5; maxalphaCo 0.5; maxDeltaT 1; Please help me to solve this problem. |
