Hi everyone,
I am fresher to OpenFOAM, and i developed my own solver. When i use the wmake command there is no error, (i think there is no error in the solver). But when i used run my case using solver the error message coming like as follows, error message:- Create time Create mesh for time = 0 Reading transportProperties Reading field p Reading field U Reading field T Reading/calculating face flux field phi No field sources present SIMPLE: convergence criteria field p tolerance 0.01 field U tolerance 0.001 field T tolerance 1e-05 Starting time loop Time = 1 DILUPBiCG: Solving for Ux, Initial residual = 1, Final residual = 4.00548e-06, No Iterations 4 DILUPBiCG: Solving for Uy, Initial residual = 0, Final residual = 0, No Iterations 0 #0 Foam::error:rintStack(Foam::Ostream&) in "/opt/openfoam211/platforms/linuxGccDPOpt/lib/libOpenFOAM.so" #1 Foam::sigFpe::sigHandler(int) in "/opt/openfoam211/platforms/linuxGccDPOpt/lib/libOpenFOAM.so" #2 Uninterpreted: #3 Foam:ILUPreconditioner::calcReciprocalD(Foam::Fi eld<double>&, Foam::lduMatrix const&) in "/opt/openfoam211/platforms/linuxGccDPOpt/lib/libOpenFOAM.so" #4 Foam:ILUPreconditioner:ILUPreconditioner(Foam: :lduMatrix::solver const&, Foam::dictionary const&) in "/opt/openfoam211/platforms/linuxGccDPOpt/lib/libOpenFOAM.so" #5 Foam::lduMatrix:reconditioner::addasymMatrixCons tructorToTable<Foam:ILUPreconditioner>::New(Foam ::lduMatrix::solver const&, Foam::dictionary const&) in "/opt/openfoam211/platforms/linuxGccDPOpt/lib/libOpenFOAM.so" #6 Foam::lduMatrix:reconditioner::New(Foam::lduMatr ix::solver const&, Foam::dictionary const&) in "/opt/openfoam211/platforms/linuxGccDPOpt/lib/libOpenFOAM.so" #7 Foam:BiCG::solve(Foam::Field<double>&, Foam::Field<double> const&, unsigned char) const in "/opt/openfoam211/platforms/linuxGccDPOpt/lib/libOpenFOAM.so" #8 Foam::fvMatrix<double>::solve(Foam::dictionary const&) in "/opt/openfoam211/platforms/linuxGccDPOpt/lib/libfiniteVolume.so" #9 Foam::fvMatrix<double>::solve() in "/home/malli_reddy/OpenFOAM/malli_reddy-2.1.1/platforms/linuxGccDPOpt/bin/myDiffusiveFoam" #10 in "/home/malli_reddy/OpenFOAM/malli_reddy-2.1.1/platforms/linuxGccDPOpt/bin/myDiffusiveFoam" #11 __libc_start_main in "/lib/i386-linux-gnu/libc.so.6" #12 in "/home/malli_reddy/OpenFOAM/malli_reddy-2.1.1/platforms/linuxGccDPOpt/bin/myDiffusiveFoam" Floating point exception malli_reddy@ubuntu:~/OpenFOAM/malli_reddy-2.1.1/PROJECT/myDiffusive$ can anyone suggest me what is the error and how to rectify it. thank you. |
