The side surfaces in this tutorial have been made symmetry planes to match the corresponding boundaries in the film region, and the top has had its pressure condition changed to totalPressure. The case now runs successfully to completion. Previously the pressure-velocity boundary condition combination on the non-film patches was incorrect in that in regions of outflow a pressure value was not being specified. This resulted in divergence.

About OpenFOAM
OpenFOAM is a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.
