Use the "Clean to Grid" filter to merge all the duplicate points before extracting the surface. So, <BR>

MergeBlocks->Clean to Grid->ExtractSurface->FeatureEdges->Clip<BR>

I would like to extract the surface mesh of a 3D tetrahedral mesh and clip off one boundary to see what is inside. This is to visualize a flow simulation around an object inside a tank. The tetrahedral mesh is partitioned into 512 subdomains so if you look in the information viewer you see<BR>
Multiblock-DataSet<BR>
Block 0<BR>
0: UnstructredGrid<BR>
...<BR>
511: UnstructuredGrid<BR>
<BR>
So far I've tried MergeBlocks->ExtractSurface->FeatureEdges->Clip and various permutations that I've seen in previous posts and the wiki, but I always end up with the surfaces on the interior of the tank as if it still sees each subdomain as a closed surface. I'm sure people do this all the time, but I can't seem to get it right. I'm wondering if I've written the data incorrectly so there is no simple way for paraview to eliminate internal processor boundaries from the domain.<BR>
