ICEM-CFD Geometry Export

June 20, 2008, 10:49

Hi, I have a mesh, from wich I generated a geometry through mesh->facets with ICEM-CFD. Now I need to export this geometry, and it doesn't work, not with IGES nor with Parasolid. That is, some simpler surfaces do get exported, but most are just ignored. Is there another way to export this geometry to Design Modeler/ Ansys? I can generate the mesh in most formats if necessary. I tried also redoing the surfaces from parametrized curves (instead of mesh curves), to no avail. Thanks,

Francois

which software are you using to view your converted CAD faces. I had used ANSA , and it had no problem in my case except that it took lots of time to read such file from ICEMCFD

I hope you need to look into other options rather than icemcfd because it is not meant for that, and it will not give a good export mostly..

I got the same problem too. I tried to export a geometry and some surfaces got filtered out. I don't know the reason up till now. Maybe, we have to find out how to turn off this filter things.

I repeat the previous posts in the thread - ICEM is not good for geometry modelling. The only reason you should be adding geometry in ICEM is just to help meshing. There should be no need to export geometry from ICEM.

Why do you want to export geometry from ICEM?

Actually, I first started meshing in ICEM. Now I have to start over in Ansys Workbench, which means using Design Modeller to modify the geometry and Meshing to mesh. I only have 1 .tin file of the geometry that I want to mesh and Design Modeller can not read it. That's why I want to use ICEM to export this geometry into .iges or igs which DM can read. If you know other way to convert the geometry file .tin to .iges/.igs which is less troublesome, please let me know. Thank you very much.

i use icem for modeling and meshing 2D geometry and i think it dose not have any problem
if your geomety is 2D so tell me what is it i mesh airfoil and cavity with icem

@fluidflow: I have a complicate 3D geometry
