You may want to be clipping the surface, not the feature edges (which should be just lines where the mesh bends sharply).

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

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
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.
