Fluent reads mesh file well, but error when mesh checking

jyoung79 · November 12, 2012, 11:25

Hi,

I am developing a Cartesian grid generation program for Fluent, and I have generated a simple 2D Cartesian mesh with hanging nodes.

It can be read well in Fluent.

When, however, I check the mesh, 'mesh check failed' is happened.

I do not understand why the mesh failed.

I have attached the zipped mesh file (aa.zip) as well. Could you check my mesh file, and give an advice, please?

Hi,
I tried to read your mesh file but I get an error when fluent opens it:
Building...

Cell Centroid is xc -4.523810 yc 6.190476
WARNING: no face with given nodes. Thread 2, cell 3

Hi,

Thank you very much for your reply.
Which Version do you use? Fluent 13 read the mesh just fine.
And I have found the fault on the mesh. Face tree was wrong.

Best regards,

Ah yes, I was still in V12, And I don't get the error with V13, which is weird!

I'm glad you found the problem.
