How to Control Aspect Ratio in Ansys meshing
 
Hi all,


I am trying to generate a mesh for Y-Plus of 1 (to resolve the viscous sub layer). The current setting i have is
  1. First layer height - 0.001 mm
  2. No.of Layers - 10
  3. Growth rate - 1.1
The mesh which i generated has aspect ratio of 1000, but i want it to maintain around 100. I am specifying face sizing to maintain the aspect ratio, but its taking too long to generate the mesh and also the mesh size is increasing exponentially.

So what is the best strategy to maintain the aspect ratio with minimum increase in mesh size.

Regards
KGN
