How to import catia modell to ANSYS APDL
This import not work properly every time. Depends very much on the version of ANSYS which you use, and version of Catia in which you made model.
I propose to you other modality of export if you have to your disposition ANSYS Design Modeller (started with version 12.0 of ANSYS is called Geometry this module - see in left panel after you will opened the WB module). Export from Catia your model using different type of export (iges, parasolid, step, etc). If you will export direct from Catia to WB, you must to have installed on your computer first Catia and after that ANSYS (to work this conversion). After you will import new format geometry in WB, you can exported without any modification using parasolid format. For me works very well in condition in which I study constant geometries with many holes, small surfaces (for example cavities from blowing press).
For other question, I am to your disposition.
