How do you apply rotational constraints when doing the structural simulation in Creo? I'm using rack and pinion from power steering system for the simulation.
Use a pin constraint. The 3rd entry is an optional rotation constraint. Use two planes to define the angle. These planes must be parallel to the pin axes.
I may have misread your question. I was thinking constraining the parts in an assembly, not providing rotational stress for analysis.
I only have the simulate light version, and I do not see rotational loads as an option.
There's a couple different ways you can do this:
What method you use depends entirely your simulate goals, the physics you're trying to model, the geometry of the problem, etc.
