Creo Simulate vs Ansys Workbench

Hello everyone.

I will appreciate if the following topics will be answered:

- How do I define the number of cells across the gap in Creo Simulate? i.e how do I manage necessary number of cells through the thickness of the modell?

- Do we have an example or manual explaining meshing in Creo Simulate?

- Is it possible to perform submodelling in Creo Simulate? 

- How good Creo Simulate is compared to Ansys Mechanical Workbench?

Thanks in andvance.

Best,

Sergey
