Hi All,


I had a simulation running with an inlet direction of ~45 degrees and the simulation converged no problem.


I had another simulation to run using exactly the same domain with an inlet direction of ~64 degrees, and an error occurs at the inlet where a portion of flow is nearly 0 and flows the opposite direction,


I have attached 4 images, the starting 45 degree boundary condition and it again halfway through the simulation as well as the start of the 64 degree boundary condition and how it looks halfway through the simulation.


Nothing has changed in the domain, I've tried re blockmeshing and SHM, but the same error occurs. If anyone could advise that would be greatly appreciated


Cheers
