dear foamers
hello, this is yong from Korea. i have researching for the project in out lab. Do you mind if i show my problem in OpenFOAM? Time = 1 Courant Number mean: 0.623268 max: 1285.63 smoothSolver: Solving for Ux, Initial residual = 0.466629, Final residual = 3.79711e+272, No Iterations 1000 smoothSolver: Solving for Uy, Initial residual = 0.470126, Final residual = 1.67436e+272, No Iterations 1000 smoothSolver: Solving for Uz, Initial residual = 0.0704463, Final residual = 2.15532e+270, No Iterations 1000 DICPCG: Solving for p, Initial residual = 1, Final residual = nan, No Iterations 1001 time step continuity errors : sum local = nan, global = nan, cumulative = nan DICPCG: Solving for p, Initial residual = nan, Final residual = nan, No Iterations 1001 --> FOAM FATAL IO ERROR: wrong token type - expected Scalar, found on line 0 the word 'nan' file: C:/OpenFOAM/cygwin64/home/experiment9/system/data.solverPerformance.p at line 0. From function operator>>(Istream&, Scalar&) in file lnInclude/Scalar.C at line 93. FOAM exiting this is the message in Cygwin terminal. i couldn't find how to solve this problem. here is p file as below, for reference. /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 2.3.0 | | \\ / A nd | Web: www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class volScalarField; object p; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [0 2 -2 0 0 0 0]; internalField uniform 1; boundaryField { inlet { type zeroGradient; } outlet { type fixedValue; value uniform 0; } walls { type zeroGradient; } } // ************************************************** *********************** // please help me to reinforce in my project. thanks. |
