<div dir="ltr"><div>Hi Gregg,</div><div><br></div><div>Catalyst will use all of the MPI ranks in the global communicator unless you pass it another MPI communicator upon initialization. It sounds like the data isn't getting constructed in the adaptor the way you think it is. You may want to try the Process Id Scalars filter to see where the data is really located and add some print statements in the adaptor to verify the behavior.</div><div><br></div><div>Best,</div><div>Andy<br></div></div><br><div class="gmail_quote"><div dir="ltr">On Wed, Jun 6, 2018 at 2:08 PM Gregg Streuber <<a href="mailto:Gregg.Streuber@aero.bombardier.com">Gregg.Streuber@aero.bombardier.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1f497d">I do have another question though. I’ve been playing around processing some data using Catalyst’s python scripting in parallel and the results aren’t quite what
I expected. What I’ve been using is a toy 50,000,000 node cube mesh with an arbitrary velocity field, and having Catalyst do some assorted processing – taking cuts etc. I’ve divided the mesh into 256 blocks using the VTKMultiBlockDataSet structure, on 256
cores. But when I load the results into Paraview it only indicates 12 VTKBlocks on the VTBBlockColors filter. There are 256 divisions in the mesh, but 244 of them are duplicates, coloured with one of the 1<sup>st</sup> 12 colours.

<p class="MsoNormal">I believe that the Catalyst examples should compile properly with all of the Catalyst editions (though I haven't tested them). If you were able to use an OpenGL with some editions then that should work for any edition that depends on OpenGL.
Are you working with a Catalyst edition build directory or an install directory? If you give me some more information on how to reproduce the error I can try and track things down.

https://blog.kitware.com/paraview-catalyst-editions-what-are-they/</a> which gives details about the editions but there's currently not a lot of details on how to make your own edition. Editing the cmake.sh script to add in more VTK filters will likely not
work as the Catalyst editions don't even have all of the source code from the ParaView source.<u></u><u></u></p>

<p class="MsoNormal">As for finding the full list of filters and modules available, the blog post has some of that but it's changed some. My recommendation would be to build an edition with Python enabled
and then use pvpython to see what's available. Alternatively you could look at files like filters.xml in the Catalyst source code to see what's there. It's not ideal but allows you to check on stuff before actually running a simulation.<u></u><u></u></p>

<p class="MsoNormal">I’ve recently installed the most full-featured version of Catalyst available on the website, but I noticed it’s lacking a lot of filters that I need very much (streamlines, for
example). I understand the installed packages are fully customizable, but can’t find any good documentation on how to go about doing this. Is this as simple as enabling different options in the cmake.sh script? And if so, is there a complete list of the
filters in paraview and the modules that contain them somewhere?<u></u><u></u></p>
