Alex, Could you specify how is your data split over time? Do you have one file per timestep? How do you load your data with ParaView? Joachim *Joachim Pouderoux*, PhD *Technical Expert - Scientific Computing Team* *Kitware SAS * 2017-11-30 9:55 GMT-04:00 Alex Barrie

Re: [Paraview] particle traces from point data

Thanks, I see it now - I missed it because it wasn't in the "Temporal" tab. When I apply this filter, however, I get an error about a missing DATA_TIME_STEPS information key. Is this something I can specify or does it have to be in the raw data somehow? Thanks, Alex On Wed, Nov 29, 2017 at

Re: [Paraview] Best file fomat for big data

I would recommend using xdmf (www.xdmf.org). It works well for large parallel datasets, and supports the same structures as vtk.ChrisOn 30 Nov 2017 10:13, a...@yandex.ru wrote:Hi! I just finish my own CFD simulation on 256 processors. The program made graphics output in 2000 time points. So large

Re: [Paraview] Best file fomat for big data

A few months back there was a suggestion on the mailing list that you can apparently write a single vtk geometry and then use something like "map data" to load the new, updated fields (perhaps Ken posted it? - don't know any other details). I agree that these vtk format limitations can be

[Paraview] Best file fomat for big data

Hi! I just finish my own CFD simulation on 256 processors. The program made graphics output in 2000 time points. So large number of outputs I need to prepare smooth animation. I use XML VTK ascii format. So I have now 2000 pvtu files and 2000*256=512000 vtu files. I have problems with such big

[Paraview] Registered texture images

Hello,   I am using python scripts to import data into a ParaView (5.4.1) session. In order to keep the texture images in a saved state, I am registering them:   pathToTextureImage='path\\imagefile' Display = Show(testvtp, renderView1) Display.SetRepresentationType('Surface') texProxy =

Re: [Paraview] Assemble Variables into Tensor

Nick, You can use the *Programmable Filter* instead with something like the following script as the *Script*: from paraview.vtk.numpy_interface import dataset_adapter as dsa import numpy def make_tensor(xx,yy,zz, xy, yz, xz): t = numpy.vstack([xx,yy,zz,xy, yz,

[Paraview] Assemble Variables into Tensor

Greetings, I have a vtk Polygonal Mesh with six separate arrays (sigma_xx, sigma_yy, sigma_zz, sigma_xy, sigma_yz, sigma_xz). I'd like to assemble these into a tensor so that I may apply the Tensor Glyph filter. After reading that the paraview.simple.TensorGlyph

Note that vtk.js is a relatively young project. That means if you are anxious to contribute to an open source community here's a chance to get in on the ground floor; we can certainly use your help. Give yourself the holiday gift of contributing to an OS platform :-) On Tue, Nov 28, 2017 at

Re: [Paraview] vtkDiscreteMarchingCubes point/cell arrays from XML-PV plugin

Hi Roman, I guess we should add some SetName() calls in the code of vtkDiscreteMarchingCubes. Feel free to submit a merge request with this very small change. In the meanwhile, what about adding a Programmable Filter on the output of this filter and do something like: inputpds =

[Paraview] post-process of CFL3D result with surfaces in paraview?

Hi paraviewers, I am using paraview to render results in CFL3D, which is in Plot3D format, including `abc.xyz` grid file and `abc.q` solution file. Besides, I have a boundary condition file `abc.xyz.fvbnd` in FieldView 1.3 format which was generated by grid pre-processor. My problem is: How to

[Paraview] particle traces from point data

Hi, I have animated particles which are imported from point data (x,y,z). I want to add a particle trace, but I am not sure what to put for the 'seed'. I am not using a vector field, but rather just a list of particle positions that updates over time. How can I just add a trace to each particle

Re: [Paraview] FEM

Paul, Welcome to the community! If your data is not in one of the large number of formats ParaView already supports, using Python to read an map to VTK data model sounds like a reasonable strategy. The "Programmable Source" would be the way to go. The ParaView Guide has examples that should help
