crpvn is on a distinguished road

I'm trying pUCoupledFoam solver from foam-extend 5.0 with backwardFacingStepTurbulent tutorial.
The solver seems to be very unstable and run diverges also with the default setup.

Does anyone have experience with this solver?
Any suggestion will be appreciated.

Thank you in advance

I wrote it ‘works for me”.

If you are running a tutorial, it must work without change. Please drop me an email and I’ll have a look.

For general guidance, you need to be careful with the outlet boundary condition. Where u is fixed, p cannot be and vice versatile. For fixedValue bc, this is clear but if you are using eg inletOutlet on U, then p condition is outletInlet
