Hello all,  
I am using vtk/paraview to process transient simulation data over a set of nodes that do not move over time. So far I have copied the same cells and points data over different files corresponding to each timeframe of the simulation and used a .pvd file to reference them. But this results in rather large files when I have many frames.  
So I am looking into a way to somehow reference a single file containing the cells and points data in all of the files that contain the frame information. Is this possible using parallel formats?

There is a ParaView plugin that works around this problem:
