Hi there,


I'm new to this forum and been using OpenFOAM for 4 months now.


I'm currently running a rhoCentralFoam solver for a CD nozzle, for this simulation I've been varying the usage of both fine and coarse meshes while also tweaking a bit their controlDict(especially with its deltaT, endTime, writeInterval). However I've stumbled upon an error which seems to be common with all of my simulations, that is this line:

mpirun noticed that process rank 1 with PID 0 on node aaron-SVS13112EGB exited on signal 8 (Floating point exception).

Now I've tried several solutions online, I've checked my mesh via checkMesh, which had a problem at the beginning, fixed it, mesh is OK but still haven't solved this error yet. I tried running on OpenFOAM debug by editing its bashrc file, but seems to be no different than before(I'm not sure if that's the way to run debug version, let me know if you know a better way), my boundary conditionsare on the proper units (Pa, m/s, and so on..)


Please help.. I'm a bachelor student writing my thesis and in one week is my deadline.

Aaron.
