Circular symmetry

Drej, I mean to say that can we make use of symmetry feature as can be done in solidworks or CATIA ?
Suppose I have created a geometry which is repeated in circumferential direction. As in my case I have to design a special gear having different tooth profile. Can I do it in ANSYS or it is better to go for different CAD package and then import it ?
Thank you

The geometry sounds like it could be fairly straightforward, and if it is, you could generate this in either your CAD package or from within ANSYS. Things to think about:
[ul]
[li]If you generate your geoemetry in CAD you will need to import this in some form into ANSYS somehow. There are many different "static" and "native" geometry formats, and whether you can import these into ANSYS depends on the type of import licence you have with your ANSYS software. By default I recall a standard licence allows import of .iges (check) but that is it and you are therefore restricted to import in this format (.iges import can be unreliable to take care; personally I prefer either Step or Parasolid format). You can generate an .iges geoemetry file from within your CAD software if you need to and then import this into ANSYS.[/li]
[/ul] [ul]
[li]If you have a standard licence you cannot import any other type of geometry or any form of native geometry format (ie native CATIA, Pro/E, Solidworks etc.). You'll need to bear this in mind before you start generating your geometry. Think also about your analysis requirements. (I'm assuming you'll want to perform some type of analysis on this structure once you've generated it, which means generating a mesh and constraints etc., so therefore think about whether it would be easier to both generate and set up the geometry in ANSYS.).[/li]
