Hello foamers,

This is my first time customizing a solver, so if my question has obvious answers, I apologize in advance. I'm adapting the simpleFoam solver to include a body force on the momentum equation, so I did all the procedures to compile a custom solver, and everything happened well. However when I started a test-simulation to evaluate the accuracy of the solver to compare with analytic results for a simple laminar steady-state flow in a rectangular shaped-brick, the results didnt go well. I've attached the log file from the simulation, and I wonder if you guys could help me with it.

I have checked the boundary conditions and found nothing wrong (I also used the conventional simpleFoam for a check-simulation to see if it was a problem with the mesh, and it ran smoothly), and I proceeded with an dimensional analysis for the added term on the right side of the continuity equation and the results are solid.

The error in the log file:

#0 Foam::error:rintStack(Foam::Ostream&) at ??:?
#1 Foam::sigFpe::sigHandler(int) at ??:?
#2 ? in "/lib/x86_64-linux-gnu/"

Thanks in advance!
