Gambit file to be opened in ICEM

I need to open a Gambit file (.msh) into ICEM CFD. I tried different ways but no luck!

I am wondering if someone can help me to figure this out.

Import the Fluent *.msh file
Yes, just go to File => Import Mesh => Fluent

Once your mesh file is loaded, you may also want to extract a faceted surface geometry from it... Edit (menu) => Mesh -> Facets.

At 13.0, you can also import a Gambit Geometry (the real parts, not the virtual stuff). File => Workbench Readers

Many thanks Simon.

Here is another question:

I could import .msh file into ICEM. It is a 3D rectangular geometry and now I wanna make a few changes without rebuilding it. I need to delete a zone and change the dimension of another zone.

Would you please let me know whether or not this is possible?

Blocking => Load from unstructured Mesh...
Sure, once you have an unstructured hexa or quad mesh loaded, and have extracted the geometry (as described earlier), go to File => Blocking => Load from unstructured mesh...

Now you have a blocking file and can edit it as per usual to split, delete blocks, change edge distributions, etc.

Import Geometry file only too Icem?
Dear All,

I created a geometry file, without mesh, in Gambit. Now, can I import it into ICEM CFD?

yes you can, use step format to export

Thank you very much.

follow these steps:

1. open file in design modeller

2. Save file either as agbd or parasolid.

3. read through workbench reader option in ICEM for agbd file or through parasolid reader.

Gambit has an ACIS kernel, and ACIS is one of the things ICEM CFD imports best... So if I were using Gambit and ICEM CFD outside of WB, I would export ACIS and read that in.

But keep in mind that only real geometry is transferred by any of these methods, not the virtual geometry stuff.

Best regards,
