Re: [Paraview] Integrate variable filter

Hello. For calculationg volumes and areas, the "Cell Data" attribute type of Integrate variables filter is usable. You don't need to define additional constant field for this. I checked it now and it seems to give the correct domain volume (554 m3 in SolidWorks, 557 m3 in ParaView). The error may

[Paraview] Integrate variable filter

Dear Paraviewers, I'm trying to compute a closed volume in paraview. For that purpose, I define a constant field with value 1 on the domain and use the integrate filter. Unfortunately the result does not seem to be correct. Attached a screenshot of the GUI where I try to compute the volume of

Re: [Paraview] particle traces from point data

I am attaching the first input file here. Each file has an incremented number in the filename and then I load them all at once using the Point3D reader. I just go to open and select the group, I don't do anything special to load them. Paraview detects them all as part of the same group, and I can

Re: [Paraview] particle traces from point data

Alex, Again, could you specify how you are loading your files? If you open them as a file series, then your data should be considered as temporal and the filter should work. See https://www.paraview.org/Wiki/Animating_legacy_VTK_file_series Best, *Joachim Pouderoux*, PhD *Technical Expert -

[Paraview] PV client-server: browsing remote files

Dear ParaViewers, I am trying to use Python shell in Client-Server mode, but I am running into some difficulties. How can I actually browse the remote directories. I tried to use the `os` module, but that obviously ends up being all local. Here's a minimal example of what I am trying to achieve.

Re: [Paraview] particle traces from point data

I was able to find this thread that mentions that maybe the input data set needs to have a DATA_TIME_STEPS key, but I am not sure how to specify this with the point3d data. https://public.kitware.com/pipermail/paraview/2016-February/036211.html Is there a way just to use whatever mechanism the

Re: [Paraview] particle traces from point data

Alex, The problem appears because the output of this Visit-based reader is a multiblock. Here is a workaround: apply a *Merge Block* filter on your input data, then apply the *Temporal Particles To Pathline* filter. Best, *Joachim Pouderoux*, PhD *Technical Expert - Scientific Computing Team*

Re: [Paraview] Integrate variable filter

You may also want to look at the Cell Size filter which has the advanced option to globally sum the values. The Integrate Variable filter can give unexpected results with mixed dimension elements since it will integrate all 0D, 1D, 2D and 3D cells. On Fri, Dec 1, 2017 at 5:02 AM, Andrew

Re: [Paraview] Writing XML VTK Binary files from C++

Another approach is to use VTK itself to write the files. Since VTK 6 it is straightforward to configure a VTK build consisting of only the IO/ParallelXML module and its required dependencies. To do so, in cmake, turn of testing, all groups and turn on Module_vtkIOParallelXML, and you should be

Hello, Thank you both for your advice. I will be sure to pursue both options and see if I can get them working. Thank you again, Nicholas Stegmeier From: David E DeMarle Sent: Friday, December 1, 2017 8:35:45 AM To: Mark Olesen Cc:

[Paraview] undefined references to EGL library functions when using NVIDIA's libEGL_nvidia.so.384.90
