Summary (AI generated)

In this text, the author discusses the maximum S Q N S angles and total mesh count in a simulation. They note that if a user were to perform an S statistics analysis, they would find that 87% of all cells occupy the prism layer region. This indicates a high level of refinement, particularly in the prism layer where 75 to 90% of total cells occupy this region. These results hold true even for both 2D ex symmetric and 3D simulations.
