[Paraview] Loading whole time series in ParaView at once

[j.dubsky at centrum.cz]

Hi Armin,
thanks  for your reply. I'm using the ParaView builtin reader. I always do "touch xxx.foam" in my OpenFOAM folder and after this I just start the paraview binary.

But actually I'm not sure if this is the problem of the reader or ParaView itself. We have the same problem when loading other data formats too. Paraview always loads the time steps one by one. This is quite annoying if you're switching from one step to the other.

I would be also happy to convert the OpenFOAM output to any other format, that would allow me to load the whole time series in memory, which would make the switching from one timestep to the other fast.

However I didn't try the option you've mention. How can I tell ParaView to cache at least the mesh in memory?

Regards

Josef
