Dear Andy, Thanks very much.
You can remap the point variables back onto the points using the Resample > with Dataset filter but that won't work for cell data. I tried the method you advised. Assuming that the original file name is A and the file after Clean to Grid and Clean Cells to Grid is B, I tried two different options for the source for Resample with DataSets and both A and B are not working. Do I misunderstand something? I believe that the D3 filter is only available if you have ParaView > built/installed with MPI.

I don't use the parallel paraview to deal with large datasets so I think D3 filter is not suitable for me. I still suggest writing out the data with either marking the repeated cells > as ghost cells or not including them in the file as any other thing you do > to get around that can become fairly expensive and manually intensive as > you go to bigger datasets. I would try to not include repeated cells in the original output file. But how to mark the repeated cells as ghost cells? I think there should a vtu/pvtu file format to describe it but I didn't find it on the internet. Could you please share it to me? BTW, when I clip a small model with 6700 elements generated by 40 processors, it looks fine. So my question: is there a limit to deal with the large dataset for paraview?
