dieselEngineFoam OpenFOAM-1.6 SigFPE error
Hi All,
I am simulation the combustion of diesel fuel using kiva mesh in OpenFOAM-1.6 using dieselEngineFoam. The fuel is injected at -30 cad (pilot) and -6 cad (main). Once the simulation reach 3.4 cad the simulation gives floating point exception error. The error shown below: #0 Foam::error::printStack(Foam::Ostream&) in "/home/keyzhi/OpenFOAM/OpenFOAM-1.6/lib/linuxGccDPOpt/libOpenFOAM.so" #1 Foam::sigFpe::sigFpeHandler(int) in "/home/keyzhi/OpenFOAM/OpenFOAM-1.6/lib/linuxGccDPOpt/libOpenFOAM.so" #2 Uninterpreted: #3 Foam::ODEChemistryModel<Foam::psiChemistryModel, Foam::sutherlandTransport<Foam::specieThermo<Foam: :janafThermo<Foam::perfectGas> > > >::solve(double, double) in "/home/keyzhi/OpenFOAM/OpenFOAM-1.6/lib/linuxGccDPOpt/libchemistryModel.so" #4 main in "/home/keyzhi/OpenFOAM/OpenFOAM-1.6/applications/bin/linuxGccDPOpt/dieselEngineFoam" #5 __libc_start_main in "/lib/tls/i686/cmov/libc.so.6" #6 _start at /usr/src/packages/BUILD/glibc-2.9/csu/../sysdeps/i386/elf/start.S:122 Floating point exception I am not really sure what actually cousing this problem. Thanks in advance. Arun |
