I have a case of a pump, some bad cells and maxOrtho 76deg. However I have absurd velocities (up to 600 m/s) right at my inlet pipem where my mesh is just a normal pipe, good mesh 😄 Velocities should be like 4 m/s. Mass is conserved at inlet patch weirdly enough My BC is flowRateInletVelocity and worked well with a very similar case last week, minus the bad cells, so I assume it comes from there, but why is the inlet affected and not the bad cells region?
