Understanding The Floating Point Exception Error Message
Hi Everyone
I'm running a CFDEM simulation coupling OpenFOAM and LIGGGHTs using the CFDEM software package and am running into some sigFpe errors. I'm looking for a bit of guidance on how to understand how this error is pointing me to the source as I am finding it a little unclear due to the ?:?? symbols. To me it looks as though the error is in the cfdemSolverPiso module [#18], however is the below telling me that there are errors in all the lines leading up to #18? Reading through the forums most examples I have seen of these errors have been a bit more clear on the source, (but I am a rookie so this could be on me!)
The simulation appears to run fine in debug mode using valgrind and doesn't throw up any errors. I am also able to solve both the CFD (using pisoFOAM) and DEM simulations separately so the issue looks to be during the coupling.

For a bit more context I am simulating a pressure driven suspension flow through a rectangular channel. I have successfully run a few similar simulations however for some reason after changing the channel geometry the below error has cropped up. If it will be helpful I can share the input files for this simulation tomorrow.
Thank you for any help you can provide!
