I am now simulating some kind of centrifugal pump using Numeca/Autogrid, and i have problems now: many overlapping cells come out on the shroud mesh. would you please tell me how to suppress those disturbing cells? i've tried some methods but i am confused what exactly to do.
what's more, what to do to obtain a no-negative-cell mesh?
Re: overlapping cells
Overlapping cells appear depending on lots of factors, may be caused by inadequate tolerance or grid cell cize definition. Pls chech your dimensional system first then increase 2 times cell size to see what will happpen.
