Hi everybody,
I want to run "dbnsFoam" on the a domain that is really just a 3D rectangle. I want to apply cyclic/periodic boundary conditions for every primitive variables and I wrote the "boundary" file that way:

However, the solver stops at the very beginning of the runTime.loop and shows:

Floating point exception (core dumped)

With GDB I figured out the problem has to come from "cyclicFvPatch::makeDeltaCoeffs(scalarField& dc)" (even though the execution seems to stop while reading "compressibleCourantNo.H" but I have no clue of what theses files are for at the moment.

Do you have any idea of what's causing the issue ?
