OUTPUT PROBLEMS for StarCd
HEY,
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, Johannes |
Hi,
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. Regards xamo |
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.

Hi,
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. Simon |
