Hello CFD Forum users,

I am currently performing some benchmarking of a solver based on OpenFOAM-dev's version of reactingFoam. I am coming across a strange issue where there is a FPE that seems related to divide by zero in the energy equation. I tried the same case with the regular reactingFoam and still got the same result. Here is the error log (using 24 cores, I've cut out the repeated messages from the other threads):

mpirun noticed that process rank 2 with PID 0 on node MACHINE02 exited on signal 8 (Floating point exception).
--------------------------------------------------------------------------

For the life of me I can't figure out where the error can be. We are not running comustion at all. What is very strange is that the case runs fine on a machine running Ubuntu 20 with OF-dev. I've been able to restart the case, and it continues for several time step writeouts later before crashing again.

Any help would be appreciated, even if its just where to look for potential issues. I am working on a test case with the same error and no confidential information that I may upload.

[mturcios777]

Just finished running serially, no crash. Have built a full debug version and will report back on the results.

The trace is too big to paste in, but the error is happening in the solve functions for PiBCG. I've attached the error log for completeness

I once had a similar problem running twoPhaseEulerFoam, and it was due some intermediate model that was unstable, causing the solution to jump across two different conditions.

Try stepping back and running with single/binary species, laminar, combustion/chemestry off. Use single step mechanism, (even if the combustion is off, because OF reads the file dont know why). Increase gradually the complexity.

Also consider starting from scratch, as you may have piled up some tests that nulls each other out. That happened to me before
