grid check failed
 
Hello,

In Gambit I made a 2D-draw. With a diffrent spacing at the edges. Then I made a volumemesh of it. And if I import it in Fluent and I check the grid it says: GRID CHECK FAILED. (it's not assymetric)

Can someone tell what to do now, please ?

Is there any message when you export your .msh file in gambit ?

Hello Steven now that you have a 3d domain meshed up did you open fluent 3d version and what was the messages you got while meshing the 3d volume

When I export to .msh it says:

A default (unspecified) continuum entity was created for 1 entities including the following: face1 Mesh was successfully written

So that must be good.

I made 2 rectagles who are united. The one has a spacing of 1 the other of 0.01. And if I decrease the spacing of 0.01 into 0.05 for example, I don't have: grid cheak failed. Maby the diffrent between 1 and 0.01 is to big?

Thank you very much to respond and help me ! Can I maybe send my .dbs-file to you?

Steven.

Hello

well it's a 2D-case and when I meshed in gambit it said:

A default (unspecified) continuum entity was created for 1 entities including the following: face1 Mesh was successfully written

And I opened the 2d-version of fluent.

I made 2 rectagles who are united. The one has a spacing of 1 the other of 0.01. And if I decrease the spacing of 0.01 into 0.05 for example, I don't have: grid cheak failed. Maby the diffrent between 1 and 0.01 is to big?
