Dear community, I need your support about my simulation.

I'm trying to do the example shown in this picture using the ANSYS APDL and I need to know from your experience if i correctly defined the problem or not.

Please let me know if you have any suggestions or corrections 🙏🏻🙏🏻🙏🏻.

To simulate the rolling motion of a loaded wheel, I defined three steps:

- step1 : the load (FZ=-75000N) is applied to the pilot node (NODENUMBER+1) and the bottom face of the support is fixed in all directions.

- step2 : angular velocity (Omgy= 1729.9450336075deg/s)and translation velocity (Vx=50km/h) are applied at the pilot node.

I applied this procedure using the following Apdl commands:
