Does anybody have some idea of how to check the mesh quality for CFX. Thanks in advance.

Re: mesh quality
There a number of options in CFX-Post such as edge length ratio, volume ratio, face angle etc.

Element Volume Ratio
I found the range of Element Volume Ratio of my mesh is between 1 to 40, and in a certain Plane, the area EVR>5 is up to 30%. Connectivity Number is between 2 and 64. (I also found in example 2, staticmixer_finemesh, has a similar situation. While according to "tool_menu.pdf" in manual, page 140, EVR higher than 5 may cause problem. I was confused.)
Sometimes I experienced problems with the flow field and convergence, is it a possible reason? How do you think the importance of EVR, CN and other mesh parameters? How can I improve this? Waiting for your suggestions and opnions. |
