Re: [Paraview] Ensight and FLUENT
Hi, I have used the fluent reader quite a bit. Basically the face zone information is completely ignored. The way that the Ensight reader handles fluid zones is to treat them as extra cell blocks. This could also been done with the Fluent reader with a small amount of extra code. I might do this sometime in the future, given enough time. However, I'm very busy at the moment! I have partially done it though. So I will follow up on this soon. I too have the problem of crashes though. If I load a multiblock fluent file, merge the blocks and then use a filter. The problem is the datasets are too large to replicate the problem simply.

Re: [Paraview] Crash when extracting surface in a big mesh
Has anyone else experienced this problem? Is it just because I have
so many cells in one block? To reproduce: compile structured grid
generator that is attached, create grid with dimensions 1000 x 1000 x
80, use clean to grid to make unstructured, and then try viewing the
surface.
Note: this uses quite a bit of memory

There is no option to start a remote pvserver from python directly.

Re: [Paraview] Poor movie quality (revisited)
This is probably due to a Windows OpenGL bug. It sounds like you have an older graphics card or you are on a laptop with intel graphics. If you turn off the light kit from the render view options OR if you turn off offscreen rendering when saving images, this should go away. -berk On Mon, Oct 27, 2008 at 9:35 AM, Renato N.

Re: [Paraview] Poor movie quality (revisited)
I'm doing other tests with a NVidia's card (with no luck yet). In fact, I was using the intel video card of my laptop (Vaio VGN-SZ430N) which was the same card used to render the movie using pv-2.6.2. The best in my opinion. Berk, I must keep at least one light turned on (headlight or the light kit), otherwise, I will get a completely dark image. I'll try copying the light kit attributes from pv-2.6.2 to pv-3.4.0.
