Dear all!

I need some help...I'm running a custom solver and it runs for a while (about a tenth of the iterations) and then the error below.

#0 Foam::error:rintStack(Foam::Ostream&) at ??:?
#1 Foam::sigFpe::sigHandler(int) at ??:?
#2 Uninterpreted:
#3 exp in "/lib/i386-linux-gnu/libm.so.6"
#4 Foam::exp(Foam::Field<double>&, Foam::UList<double> const&) at ??:?
#5
at ??:?
#6
at ??:?
#7 __libc_start_main in "/lib/i386-linux-gnu/libc.so.6"
#8
at ??:?
Floating point exception (core dumped)

Best,
Sandra

1. Don't panic.
2. Start reading here: Foam::error::PrintStack - post #2
3. Still can't figure out the problem, then read here: Parallel running of 3D multiphase turbulence model (unknown problem!!) post#3
4. Perhaps wrong dimensions? porousSimpleFoam - crash post #2
5. Wondering what it all means? Here's an explanation of one example: Unstabil Simulation with chtMultiRegionFoam post #11
