[Paraview] extracting the surface between filters

Wed May 19 08:54:01 EDT 2010

Hmm.  Now that I think about it, all my datasets with quadratic elements are surface elements, so this problem wouldn't show up.  The other test data sets have 3D quadratic cells, but without any neighbors.  Is there a simple small example you can post?

Hi,

After some more digging around this problem, it seems that it only shows up for quadratic cells.
It might be related to the recent evolution I saw where the wireframe representation of quadratic cells are not triangulated anymore (which is nice!).
Are there quadratic cells in any test file (in ParaViewData) so that I can try to reproduce it with it?

Best,
Stephane

Re: [Paraview] extracting the surface between filters

I cannot replicate that behavior.  I've tried loading the ParaView data files bluntfin, disk_out_ref, and RectGrid2.  I've tried them on the current git pull, 3.8.0-RC1, and 3.8.0-RC2.  It works as expected every time.

Hi all,

I am seeing a bug recently that is puzzling me :
It seems that the surface of the datasets is extracted between two filters.

For instance, I setup the following pipeline :
reader -> shrink

The first time this is executed, I see the shrink of the border cells.
If I do the following manipulation
*mofidy any parameter in the reader,
*unmodify this parameter
*and click on apply
(the result being that no change is actually sent to the server, which I can check because the RequestData method is not called again in the reader),

then the shrink filter is refreshed and gives me the good output (the internal cells shrinked).
Has anybody else seen this?
