Hi Foamers: I am simulating the flow over a stepped spillway using OF version 2.2.0
The flow is simulated using pimpleFoam solver and RANS approach (v2-f model). I did the geometry in Autocad and exported as a stl file. SnappyHexMesh works fine and my mesh is ok.

My model runs OK but... when I change the pressure BC in the upper part (surface) from zeroGradient to fixedFluxPressure I have the following error (segmentation fault):
