[Paraview] Doubt about animating 2 (or more) datasets simultaneously

[Renato Elias]

Thanks a lot for the explanation Ken. This question came to my mind when I
thought about visualizing 2 simulations at the same time (and in the same pv
session, of course). One using fixed time steps and the other one using
adaptive time steps.
