Hello,

When I export my mesh from Gambit, everything works fine. And it reads into Fluent normally too.

However when I do the grid check in Fluent, it fails and i get the normal Warning: Grid check failed business.

But there are no negative volumes anywhere and no other warnings whilst the grid is being read into Fluent.

It's 5 3D volumes connected and meshed using Tet/Tri

Can anyone help? Thanks

Adding to that,

I DO get this when my grid is being read into Fluent.

Checking node count.

Incorrect node count (308857 != 308837)

Is this causing the grid check to fail?

i dont think the "Incorrect node count" i sthe reason for the grid failure...it would be something else....or do this, change ur boundary conditions to whatever u want to and then do the grid check again...sometime fluid dont agree with ur defualt bc...

Thanks Hassan bro, I'll try that

If that doesn't work, you may want to try re-ordering your nodes Grid > Re-order > Domain. I sometimes find when I'm exporting from ICEM that the Fluent grid check fails on node count unless I re-order the nodes. It's a good habit to get into anyway if you're solving the domain on parallel processors

Thanks Tim,

I tried doing that, twice until the value gets to about 1 but the grid check still failed.
