Gridgen to Fluent
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

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 for detailed diagnosis.
