Non + Vol
 

hi everybody:)
I make a complex 3D-geometry in gambit,(also meshed it there)
then I read this file with fluent! there is a problem . when I check grid I receive this [WARNING: non-positive volumes exist.]!:eek:

I think that maybe gambit badly meshed but I dont know how can I correct that?[this is the first time i receive this error:confused:].

I look forward for Ur answers!:)

Check where is your cell(s) with negative volume.
In gambit go to examine Mesh, choose Volume and set the upper limit to 0.
Then you need to perturb your mesh parameter to correct your issue (with a size function for instance)
