Dears,
I am trying to use PyFR as a tool for my research. However, I am having some difficulties to obtain simple results in a 2D backward-facing step flow case. I have tried to run this case considering incompressible and compressible flow. However, even I reduce the Courant number (reducing the time step or the inlet velocity), I am obtaining NAN residues.
Please, could you configure this setup (backStep.ini and backStep.msh are attached) and give some feedback about the mistakes I am committing?
Thank you in advance,
Best regards,
