Gambit export file not created

Amit Verma · January 21, 2010, 13:02

Hi Everybody,

I am making a mesh for a laminar flow problem through a pipe. So I created 4 vertices>>edges>face and finally I made a mesh. then I specified boundry types.

After that I saved the file. But when I try to export to it gives the following error and warning.

"WARN: Boundry Entity Centerline does not contain any valid entry and is not written.

No Entities were found for mesh export.

Error were found during export. Export file was not created. "

However the centerline is edge 4 of my mesh and I have done a valid entry.

Kindly help in this regard.

Amit

You have to specify create a 3D or 2D mesh and in your case 2D?
I think there is in the mesh export window a small button...

Yes I had clicked 2d...while exporting.....but still.. the problems remain!!

Ur mesh is wrong.
U cannot just mesh the edge, u need to mesh the whole surface.

Ur running on 2D simulation right?
