Hello,
Simulate lets you perform analysis using symmetries (either cyclic or mirror). The problem is that in order to use symmetries, you have to create the part or assembly using Creo.
It should be cool if simulate allows you to cut or remove material from a non-creo model. In that way, you can simulate a turbine modeled in Catia or Solidworks using symmetries, avoiding that your computer fries with each blade.
That's all.
