why icoFoam show "Floating point exception"?
 
Hello everyone,
recetly ,I still use icoFoam to calculate a channel flow.
I use ICEM to generate a struct mesh,Then I use fluent3DMeshToFoam to make the polyMesh dic.
But when I run icoFoam,it can not go even one step.
It shows;

#0 Foam::error:: printStack(Foam::Ostream&) in "/home/wh/OpenFOAM/OpenFOAM-2.1.1/platforms/linuxGccDPOpt/lib/libOpenFOAM.so"

have you tried running checkMesh already? What is the output?

yes ,I make a new struct mesh.Now it seem that icoFoam can run.

see this link:

before this error what warning appeared?
