I'm trying to write an output file for StarCD version 4.08
But i always get this problem.

"Error: running ansys icemcfd -star-4 Interface vers.11.0.1
Error exit: this interface only supports 3d meshes!
Error in translation...
child process exited abnormally"

Do you have any idea to solve this problem?

Thank you very much,

as far as i know (Star 3.xx) you need a 3D mesh for STAR, it cannot handle 2d meshes.

So do your 2d mesh in ICEM and extrude it one layer, so you receive a smiple 3d mesh. This can be exported to STAR and can be calculated as a 2d mesh.

Or use an older version of StarCD...
STAR-CD 3.2 supports 2D meshes, but apparently not STAR-4. Try using the STAR-CD 3.2 format which STAR-4 can probably read...

To be clear
To be clear, the problem is with the ICEM CFD output interface, Star-4 should be able to support a 2D mesh if writen out from ICEM CFD in STAR 3.2 format.

You can read in 2d Meshes in Star 3 and Star 4. But you only will have 2D shells in STAR. You can have a look at them and move them but for a calculation in Star you need a 3D mesh.

Correct me if i I am wrong.

Regard xamo

Not a Star Expert...
I havn't been a regular STAR CD user for about 8 years, (Using Fluent and CFX since then) so you may be right. I just knew they could read the format, so I was giving the benefit of the doubt.

If Xamo is right about StarCD, then I agree that extruding the 2D mesh into a single cell thick 3D model is the best plan. That is how I would do it for CFX.
