Utkarsh:
Thanks. That did the trick. I had to add a 'Threshold' filter in the mix
to remove the ghost cells, which were confusing the 'Merge Blocks' filter.
I've actually been staring at those boundary lines for over a year and a
half and I've very glad to finally have them gone
Again, thank you very much.

When you do "Merge Blocks", it will merge all the blocks into a single<br>
unstructured grid. This will make it possible to get a more reliable<br>
CellDataToPointData conversion across the block seams and hence avoid<br>
the seams on contouring.<br>
