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.

Hi there!

Also have this problem when running the SadiaD_LTS case in v7...
Is your case EDC combustion?

Not a solution but what I found is that if you go to your controlDict and change the start time to the time at which the simulation crashes and retype reactingFOAM, the simulation actually runs and finishes.

Hope this helps somehow.
