[ANSYS Meshing] Details of Mesh Statistics

akash_max · October 31, 2011, 09:06

Hi All,

Please find the details of the mesh statistic below. I usually get confused with this.
Could any one explain me more on this. By seeing this statistics please let me know what should i do the corrections and how could I improve my mesh using workbench.

I didnt get good convergence with this mesh. It take lot many iterations before it reaches below RMS 1e-05, atleast where I can stop and postprocess my results.

Kindly help me on this

Best Regards
Akash

1. KEEP the minimum angle greater than 20 (MUST be done)
2. Also take care of expansion factor that is the ratio of two adjacent cells. Should not be greater than 10-20 I guess. Check the CFX help
