Rolling Contact Simulation & Analysis in ANSYS

Hallo... I am the final semester student of bachelor mechanical engineering. My final project is Drum Brake Simulation Using FEM in ANSYS.i know how to use ansys but only a little bit. Model for drum brake is 2D like donut or circle for drum and shoe.  I have problems now..How to rotate or spin that model in ansys. Please give me a step by step tutorial to rotate or spin 2D model. i tried b4 and I can't get the simulation. That is the important thing that I have to do first. Later I have to solve the contact analysis between shoe and drum. If u guys had done it or tried the simulation before,please send the file to my email or reply and discuss in this forum. thanks you very much.. For everyone who expert in ANSYS, please help me..

Regards,
