Hi, everyone.

I'm new using OpenFoam, I have been trying to run a 2D case, it's a pipe with a reduction. But when I use simpleFoam, throw me this error:


#0 Foam::error:rintStack(Foam::Ostream&) at ??:?
#1 Foam::sigFpe::sigHandler(int) at ??:?
#2 ? in "/opt/openfoam30/platforms/linuxGccDPInt32Opt/lib/libOpenFOAM.so"

I check the mesh several times and use checkmesh, also I have changed the initials properties (p, U, k, epsilon) and controlDict files but the error continue.

This is blockMesh information:

If someone can help me, I'd appreciate it.

Hi Sergio,

The "back faces" after the pipe reduction are not assigned to any patch.

Hi Carla.

You are right, I forget to define those faces.

Thank you very much.
