I am failing in getting an resonable start solution from potentialFoam, I get exploding velocities at sharp corners around the stagnation point. No idea why this happens, similar cases ran fine. PotentialFoam takes all the allowed pressure steps (100) whereas for similar cases before he took about 50. An idea? Regards.
