Hello Everyone,

I have an output file in Tecplot format that I’d like to postprocess in ParaView, specifically to create an animation. Currently, I can only load files from all my processors for a single time step and then use the Group Dataset or Merge Time filter.

Could someone please advise me on how to load all time steps simultaneously so I can view them continuously and create an animation?

The file output naming is like “input.contour.ts000tttt.part0000nn.dat” where t is the time step and n is the proc number.

Thank you!
