Spatial discrete algorithms based on the finite element method rarely if
ever require ghost cells extending beyond the physical boundary.
Algorithms based on finite difference technology almost always require a
layer of ghost cells around the analysis domain to allow the

Thanks for correcting me. I'll try adding the vtkGhostLevels to the
XDMF and see how that goes.

The right way to deal with this situation is to mark the ghost cells
as ghost. If you create a cell array called vtkGhostLevels and
MergeBlocks-CleantoGrid-ExtractSurface-Clip
should work for you in 3.4. If not, there is something else wrong. I
would like to see a dataset. I think we can make the whole thing work
without MergeBlocks and CleanToGrid if we required that you define a
vtkGhostLevels array that is point centered.
I constantly have the same problem than you removing the parallel
interfaces. Even worse, since my solver does not use ghost cells at all.
BTW, try to execute the following pipelining in ParaView *version 2.2.1*.
Extract Surface -- Clean to grid -- Clip
Not sure if it also works with Xdmf
Hi Chris,
Use the Clean to Grid filter to merge all the duplicate points before
extracting the surface. So,

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

Hi,
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
