I have been encountering a problem. When I am doing simulation of a pump with a coarse mesh (cell size: 0.05 m) the simulation runs fine. There is an error warning that " Hard points are not supported and might be ignored in the 3D pre inflation " . I disregard this warning and it runs fine.
When I decrease the cell size to to 0.035 m, it gives me the same error warning plus error at the interface when i try to run the simulation. I had a similar error in the solver before but I reduced the impeller-volute domain interface tolerance to 1 mm and it worked fine. Now that I want to have a grid independent study, the solver does not let me.
The error is included in the attachment.

The error was resolved when there was absolutely no tolerance between the rotor and the stator interface.
