[Paraview] PV 4.1 How to extract a slice for z= constant

[Moreland, Kenneth]

The subject line of this email asks how to extract a slice in a z=constant plane. That can easily be done with the slice filter with the normal set to 0,0,1.

The text of this email asks a completely different question, extracting the exterior boundary of an unstructured mesh. This is done with the Extract Surface filter. If your data is distributed with MPI and does not have ghost cells (which is common in unstructured data files) it is possible that Extract Surface will also extract some interior surfaces at the boundary of the geometry partitions. If this is a problem, you can first use the D3 filter to generate ghost cells and then run the Extract Surface filter.

The mesh is unstructured, PV running mpi.
The mesh is rectangular.
I would like to extract an exterior boundary.
How does one do this?
Thanks,
Stephen
