Simulation aborted with reactingFoam
3 Attachment(s)
Hello,
I am trying to simulate a burner, my geometry is basicaly a pipe with an entry of methane and multiple entry of air around it. I use realizable k epsilon turbulence model and i launch my simulation in parallel. The solver used is reactingFoam.
Unfortunately my simulation keep aborting with this error shown in the terminal after doing 11 iteration with 0.00001 time step:

mpirun noticed that process rank 0 with PID 0 on node ubuntu1 exited on signal 8 (Floating point exception).
I attached my "chechMesh -allGeometry -allTopology", fvSolution and fvSchemes files.
I don't know how to correct this, if anyone already had to face this problem and could help me, it would be nice !
Thank you. |
