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/"
#1 Foam::sigFpe::sigFpeHandler(int) in "/home/keyzhi/OpenFOAM/OpenFOAM-1.6/lib/linuxGccDPOpt/"
#2 Uninterpreted:

#4 main in "/home/keyzhi/OpenFOAM/OpenFOAM-1.6/applications/bin/linuxGccDPOpt/dieselEngineFoam"
#5 __libc_start_main in "/lib/tls/i686/cmov/"
#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.
