icoFoam - error with surface interpolation?
 
Hi

I get this error using icoFoam:

#0 Foam::error::printStack(Foam::Ostream&) in "/home/bernarde/OpenFOAM/OpenFOAM-1.6/lib/linux64GccDPOpt/libOpenFOAM.so"
#1 Foam::sigFpe::sigFpeHandler(int) in "/home/bernarde/OpenFOAM/OpenFOAM-1.6/lib/linux64GccDPOpt/libOpenFOAM.so"
#2 ?? in "/lib64/libc.so.6"
#3 Foam::surfaceInterpolation::makeWeights() const in "/home/bernarde/OpenFOAM/OpenFOAM-1.6/lib/linux64GccDPOpt/libfiniteVolume.so"
#4 Foam::surfaceInterpolation::weights() const in "/home/bernarde/OpenFOAM/OpenFOAM-1.6/lib/linux64GccDPOpt/libfiniteVolume.so"
#5 main in "/home/bernarde/OpenFOAM/OpenFOAM-1.6/applications/bin/linux64GccDPOpt/icoFoam"
#6 __libc_start_main in "/lib64/libc.so.6"
#7 _start at /usr/src/packages/BUILD/glibc-2.9/csu/../sysdeps/x86_64/elf/start.S:116
Floating point exception

I have no idea how to debug this. It looks like it might be something to do with the surface interpolation?

My log file stops at:

Reading/calculating face flux field phi

Can anybody help me figure this out?

Thanks

Hello,

I know this is a few years old, but I am getting the same problem on a project i am currently working on.
Did you managed to figure out how to fix the error?

Thank you

Hi;

May be you already found a solution or are still looking for one. There is a possible chance from the 1st line that somewhere in your modified code, you are dividing the value with 0 and thereby the variable that is being computed is giving you this error.
