Hi gitpicker85
Please ensure that the version of ANSYS that you are using supports Inventor eg ANSYS 11.0 supports Inventor R10 and R11.
You will also need valid licenses for both Inventor and the ANSYS Geometry Interface for Inventor.
Next, Inventor has to be installed on the same PC where you are using ANSYS, and it has to be runned once, before installing ANSYS. This means that you must be able to use Inventor on this PC too.
When you install ANSYS, please make sure to select Geometry Interface to Inventor/MDT (this is automatically selected if detected).
Now, when you use ANSYS Workbench, you should be able to import the Inventor model.
If you don't have both the Inventor and ANSYS Geometry Interface for Inventor licenses, then your option is to have your partner provide you the model in either STEP or IGES formats.
Lastly, if you have an ANSYS Geometry Interface for SAT license, then you can have your partner provide you the model in ACIS SAT format.
Regards,
Tim
