FAQ: How can I get less transitions between coarse areas and dense areas?
How can I get less transitions between coarse areas and dense areas?
If you donít use a level per part which is the best way, you can use Auto, reduce the base level and restrict the range. eg: baselevel: 60 range 1-3 instead of baselevel: 120 range 1-4
This usually gives same number of cells but less transitioning. This is good for k-ε solvers which do not like the levels changing a lot.This will also help with boundary layer generation.
You can also set the expansion on fast globally, and use the per part expansion in advanced to make it slower on different parts
