Hello Matthias,
I don't know if there's a full documentation of ParaView plugins
(they call them filters), but I simply go through the drop-down list
of available filters (menu Filters->Alphabetical) and look if there's
anything potentially useful for me. Most filters are available by
default, you can control what is loaded at startup in Tools->Manage
Plugins.
Most of the time, I use:
- Transform to scale the mesh when I need it to be in different units
- Clip to remove a part of the mesh
- Extract cells by region (a bit similar to Clip, but preserves
cells, does not cut through them)
- Tetrahedralize (takes a hexa mesh and splits all elements into
tetra elements)
- Extract surface (similar to the skin plugin that prof. Geuzaine
mentioned in his reply to my post)
I believe you can also use vtk as a library and link it to your own
code to have all the filters available.
It's hard to process meshes with one opensource package, I usually use
the combination Gmsh-Paraview-Meshlab. I like gmsh, but its gui
becomes extremely slow with large meshes (say ~ 10^6 elements).
ParaView is much more responsive.
Best regards,
Martin Vymazal
Quoting "Zenker, Dr. Matthias" <[email protected]>:
Hi Martin,
I have read in your message below that one can modify a mesh with
ParaView. I use ParaView for postprocessing and didn't know that it
can also process meshes. Maybe this could help me to solve a meshing
problem I have since a long time which gmsh cannot solve. Could you
give me some indications where I can find information about
ParaView's mesh processing capabilities? Are there built-in filters
for that (which ones?), or did you need to build one yourself?
Thank you for some hints,
Matthias

Betreff: [Gmsh] Reclassify 2D does not work
Dear gmsh developers,
I have a 3D flat plate grid downloaded from here:
http://turbmodels.larc.nasa.gov/flatplate_grids.html (3D Plot3d
grid, 2 x 545
x 385 points). I converted the grid to vtk and also split the hexahedra into
tetra using paraview. I am not able to reclassify the surface of
the geometry
to create physical surfaces (to be able to set boundary conditions
for my flow
solver). The 'Reclassify' button in the Reclassify2D dialog always remains
greyed out, no matter what I do. Is it a bug? If not, could you
please tell me
the settings you use to reclassify the surface?
Best regards,
Martin Vymazal
