>How can be obtained the geometry. Is it possible?
No. Once you switch your model from Workbench to ANSYS, you lose all of your geometry, and only the finite element information is retained. To see exactly how the information is switched, see the ANSYS command CDWRITE. To get your geometry into ANSYS either (1) obtain a Pro/E native import licence or (2) write out a static file from Pro/E (iges, step, ...) and import this into ANSYS.
