[Paraview] [EXTERNAL] Time Synchronization for Case and Geometry Sequences

[Moreland, Kenneth]

Actually, I think Sequence mode is more appropriate than Real Time mode in this case, but I too think that is the answer. 

To explain more what (we think) is going on: When you load data with time in ParaView, it goes to a Snap to Timesteps mode where it will visit each unique timestep once regardless of how far apart they are. Thus, ParaView is treating the numerical imprecision of the different times as unique time steps. If you switch to Sequence or Real Time mode, ParaView uses its own time units and will provide an even temporal spacing. 

There is more information about the different animation modes in the ParaView tutorial.
