Gridgen to Fluent

bro6789 · November 26, 2009, 11:25

Hi everyone,

I created an unstructured grid using Gridgen and tried running it in Fluent. However, Fluent gave me an error saying that there were non-positive volumes when I ran the grid check. Somehow the max. volume recorded during the grid check was also negative. I tried reordering the domain in Fluent but that didn't solve the problem. Any suggestions?

Thanks in advance

Bro:

It's difficult to diagnose the problem with the information provided. First, are the volumes positive when computed in Gridgen using the Examine command?

As always, I recommend that you contact our Tech Support engineers at support@pointwise.com for detailed diagnosis.
