RES: [Paraview] I only want to see the bodys in a 3d-unstructured grid

[Renato N. Elias]

If I understood your question you're trying to extract and show the body's
surface from your solid mesh, is that correct?! If my understanding of your
question is right, It's something that PV does nicely. Thus, assuming you
have a tetrahedra mesh with everything minus your body (I use to calling it
"femme" model or "negative" model), you'll need to extract the surface
through the "extract surface" filter and then apply the "clip" filter in
order to cut out the outward surfaces and show only the inward surface (the
body you want). If you already have the outward and inward surfaces, you
only need to apply the clip filter.

NOTE: You'll need to select a suitable "clipping function" (the box function
is good for it) and set the "inside out" option accordingly.

Cheers

Assunto: [Paraview] I only want to see the bodys in a 3d-unstructured grid

Hi
 
I do have an unstructured grid (saved in vtkXML-format). This grid surrounds
some kind of bodys (in my case wings and stuff like this). The surface of
the bodys is discribed by surface-triangles and -quads. I only want to have
a free look at the body´s surface, but I still need the surrounding grid for
streamlines and so on. -> I want to have something like you can see on the
Paraview-Screenshot-page - picture called "CFD analysis of the..."
(http://www.paraview.org/Art/BigShot12.jpg)
My problem is the following:
When I do make an (Banded)SurfaceMap Paraview still presents the surface of
the surrounding grid (although there are no surfacetriangles or -quads) and
this surface is of course in the line of sight to my body. I only want to
see the surfacetriangles and quad of my body!
 
Does anyone has an idea how to manage it?
 
Thanks
 
Steffen
