[Paraview] display boundaries of 2D geometry

[Samuel Key]

Matthias,

An approach that works well for me is to exploit the "Part" feature in 
either the VTK-formats or the EnSight format.

The "Part" construct in the VTK XML-format looks to me to have 
originated based on the need to combine for ParaView a set of results 
generated from individual CPU's. It can also be used for an assembly of 
parts. In my case, material domains are used to define the "Parts." The 
PV Extract Block filter displays the user's part names and can be used 
to display any combination of "Parts."

Again in my case, it is important to know that point-sets, and element 
edge-sets  and face-sets at time(0.0) are properly defined. At 
time(0.0), a mesh-by-material, point-sets, edge-sets, and face-sets (aka 
side-sets) are generated, all based on the "Part" construct, for the 
express purpose of visualizing these in ParaView before a simulation is run.

The key to doing this is to understand that each "Part" needs to be a 
complete, standalone, displayable graphics object.

Should you or your staff be interested in exploring this approach, a set 
of FORTRAN language routines can be provided.
