Re: [Paraview] Average data from multiple nodes
Alan, Try selecting the points you want and then plot the selection over time.

[Paraview] Memory use with Xdmf files
I have written an Xdmf file that uses the 3D CoRectMesh to display a montage of 54 gray scale images. They are laid out in a 9x6 fashion. Each Image is about 1292x968 pixels. We have run stitching algorithms on the images to find their correct coordinates in XYZ space so that they will form the montage correctly. The raw amount of memory is 67,535,424 bytes. If that has to be as RGBA for rendering then it is 270,141,696 bytes. Then ParaView has to create a cell for each pixel and then some other stuff. At one point ParaView spiked to 120GB of RAM and then fell back to about 36GB of RAM. This seems a bit excessive to me. This is with ParaView 4.3.1 on a Windows 8.1 workstation. Am I doing something wrong? Just seems like a lot of memory. Are their alternate ways of writing the Xdmf file so that each image is a single cell perhaps? Thanks for any insights. I can make the data set available to anyone who needs it. _ Mike Jackson mike.jack...@bluequartz.net BlueQuartz Softwarewww.bluequartz.net Principal Software Engineer Dayton, Ohio ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview

Re: [Paraview] Average data from multiple nodes
Huh. I'm thinking of the behavior described in bug 0014940. When you make a query selection, you get statistics like average. When you make a surface selection (which is essentially an id selection) you get that first point. When you make a frustum selection, you get an error. I would report this as a bug. I expect the plot selection over time to be consistent over all types of selection. And I would want the behavior to be as described in bug 0014945. -Ken From: Scott, Walter Scott wasc...@sandia.govmailto:wasc...@sandia.gov Date: Friday, January 30, 2015 at 11:04 AM To: Kenneth Moreland kmo...@sandia.govmailto:kmo...@sandia.gov Cc: paraview@paraview.orgmailto:paraview@paraview.org paraview@paraview.orgmailto:paraview@paraview.org Subject: RE: [Paraview] Average data from multiple nodes Ken, I don't think that works.

Re: [Paraview] ParaView Seg Faults when running Animation in a Programmable Filter

Any thoughts?

I'm not even sure this is a ParaView issue, but I'll still share my story in case someone has any insights that they can kindly share. My Programmable Filter code works fine for the Current time step, regardless at which time step I run it (i.e., hit the Apply button of the Programmable Filter). However, when I hit the Play button to loop over time steps (which appends some information to a CSV file), ParaView seg faults after reaching the /3rd time step/. The filter has been working for some time and this started to happen all of a sudden, without any system update. It may be related to a weird combination of hardware, software, and drivers. My script works fine on a desktop computer I have but it seg faults on my main workstation, which has an AMD/ATI Radeon R9 280x GPU running on Linux Mint 15, 64-bit. When I completely removed the AMD drivers, it still seg faulted but after reaching the /6th time step/ after the current one. Then, I launched an Ubuntu 14.04 LTS 64-bit, live on a USB flash drive. The script in Programmable Filter worked perfectly fine. As a result, I installed the OS, but it acted up exactly as the Linux Mint installation. The input files are massive vtk unstructured grids (about 800 MB each). I created smaller files, but unfortunately I couldn't reproduce the error. But I'm fairly sure that the files are not corrupted. As such, I can't send out the files that cause the issue. I also monitored the memory usage using free -h command while Playing.
