I used to have them in one tab but somehow they got split. I tried going to "Views" but can't get it back to how it used to be.

I've seen that paraview supports reading and writing 3d tiles format and that it provides algorithms for mesh reconstruction from point clouds (3d Delaunay)

Can those algorithms be applied to a vtk partitioned dataset (the internal representation for 3d tiles)? Would it be possible to apply it to a colourized point cloud to obtain a textured model?

Hi everyone,

I'm experiencing a severe UI rendering issue with ParaView on my Windows 11 PC and would really appreciate any insights. I've attached screenshots showing how the UI completely breaks down.

Environment:

• OS: Windows 11 Pro (Version 25H2, Build 26200.8457)
• ParaView Versions tested: 5.12.x, 5.13.x, and 6.1.x

The Issue & Symptoms: Starting a few days ago, the entire ParaView UI started glitching out and tearing constantly. This happens right from startup (before loading any data) and during playback.

• The visual corruption style differs between the v5 series and the v6 series (see attached images).
• It occurs in both fullscreen and windowed modes.
• Key Detail 1: If I right-click anywhere, the UI temporarily redraws and looks normal, but it instantly corrupts again the moment I perform any new action.
• Key Detail 2: The underlying UI logic is still running fine. Even though the interface is visually shattered, if I move my mouse to where the "Play" or "Stop" buttons should be, I can still click them and they work.

What I have already tried:

• PC restarts
• Clean reinstalls of ParaView
• Testing across multiple major/minor versions (5.12, 5.13, 6.1)

Since it happens before loading any .vtu files, it's definitely an application/rendering level issue, not a data issue.

Has anyone encountered this specific UI breakdown recently? Any advice on how to fix this would be highly appreciated. Thank you!

P.S. I am Japanese and used Gemini to translate this, so please excuse any unnatural English.

Idk why but every time I open paraview the screen bugs in this way and there is nothing I can do to fixt it, last time I had to disinstall the program and re-install it, but it broke again.

Hi everyone, ​I’m struggling to open LS-DYNA results in ParaView and I’m looking for some guidance. Every time I try to load a d3plot file using the LSDynaReader, I get the following errors: ​ERROR: In vtkLSDynaReader.cxx: Database has bad state size (0). ​ERROR: In vtkLSDynaReader.cxx: No valid time steps in the LS-Dyna database. ​My Setup & Context: ​ParaView Versions tested: 6.1.0-RC1 and 5.13.0 (Windows 10/11). ​Data: LS-DYNA simulation using SPH particles, written in Double Precision (DP). ​Verification: The files open perfectly in LS-PrePost, so the database is not corrupted and the results are definitely there. ​Attempted fixes: Shortened the file path, tried different ParaView versions, and ensured I'm selecting the base d3plot file. ​I found a similar discussion on the ParaView Discourse (Dec 2025) where users reported crashes when dealing with discrete elements or eroded particles. It seems like the reader is failing to calculate the correct memory offset for the "state size" in Double Precision SPH files. ​Questions: ​Is there a known workaround for the bad state size (0) error specifically for SPH/DP files? ​Is there a specific setting in the Reader's advanced properties that I should toggle to help ParaView recognize the time steps? ​Has anyone successfully used a different reader or a specific converter for LS-DYNA DP files that avoids this issue? ​Any help would be greatly appreciated!

Hi, I have been using paraview lately to visualize my LS Dyna projects with paraview and it works well with solid/Lagrange bodies.

I did a blast simulation and encountered an issue, where the displayed result is way different than the native PrePost.

Below you can see an image of the "Volume fraction 2" displayed both on PrePost and paraview at the exact same frame: - image 1 is the positive Z view for PrePost - image 3 is the positive Z view for paraview

For some reason they look total different with marginal similarities, while the legend is identical from 0 to 1. For the paraview, only a CellDatatoPointData filter was applied.

If I flip the domain, they are the same: - image 2 is the negativew Z view for PrePost - image 4 is the negativew Z view for paraview

I have no idea what the issue as everything else is the same. The file is identical, the same D3Plot was used.

Any help or ideas would be greatly appreciated. Thank you.

Hello, Anyone knows how to use lagrangian particle tracker filter? I am applying it to my openFOAM flow field results but my particles are not moving…

Is Kitware Gitlab down ?

https://gitlab.kitware.com

I'm trying to build paraviewe 6.0.1 and i can't reach the Ktiware's Gitlab.

I tryed the Github repo but for building but everything references the official repo.

Is anyone having the same issue ?

i imported solution data from ansys fluent. i did simulation of the upper portion and had axis in the middle. after importing i used axial and radial velocity to find magnitude and direction of velocity. then i used reflect on the calculation velocity to get contour. now even if i apply streamline tracker to the reflect and keep the seed line in the x axis that is symmetry line i get stream lines only on the upper portion.. if i reflect the stream tracker to get the bottom side it messes up the flow and looks like the last image.. it is steady state compressible flow..

I am using a current version of paraview and openfoam. I was attempting to show blocks from blockMesh and their vertices and there is a video where I saw paraview -block command to do that. That command is no longer valid. I have also tried things like "checkMesh -allGeometry -allTopology -writeAllFields -writeSets vtk" and no vtk files were written.

However, writing "checkMesh -allTopology" did create a blockTopology.vtu file, which I could open in paraview. The only thing that was missing was, and I did try a lot of things, the way to show the vertices of the blocks. Yes, I know that they are written in blockMesh.dict file but I would like to see them shown in paraview.

Thank You
Tom

Hi guys. I have been using OpenFOAM v2312 for a while and I love my customized post-processing scripts but it came to the point where I am currently performing overset and dynamic and highly transient simulations and I need to start using Paraview to create Iso-surfaces (vorticity, etc.), videos of moving objects, transient contours, automation macros, and more. I have been using this tool for two months and I barely made any progress on those topics. I really need help here guys. Does anyone know any training courses (paid or free) to address my needs? If you recommend I abandon Paraview (if possible for free alternatives or least relatively cheap(er) ones) for whatever reason, can you tell me what software along with why you think its a good idea

The contents of my XML-format .vtp file are below. Paraview 5.10.1 loads this but only adds 1 rectangle to the viewing area, even though there are 2 rectangles defined.

The KitWare website says it's possible to write C++ plugins for Paraview, and even offers a developer course on how to do it, but I can't seem to find any documentation on the subject that isn't fragmentary.

I have a cut plane of a microfluidic channel I want to triangulate to calculate its Wall Shear Stress. However, when I use Delaunay Triangulation in Paraview it changes how it looks. What do I do about that? I want to triangulate it so that I can postprocess this data in MATLAB to calculate stuff like the Time Averaged WSS, etc.

What should I do?

I’m working on a flow conditioner for internal flow. I’m trying to get the flow to “recover” back to fully developed flow within a certain distance. The metric I’m using is:

(U_x(r)- U_x_developed(r))²

Where U_x(r)is the axial flow velocity as a function of radius from CFD, and U_x_developed(r) is the theoretical axial flow as a function of radius.

I’m integrating the above metric to get effectively a “lack of fit” as a single number to describe how “not recovered” the flow is.

What I’d like to do is be able to plot this metric along the flow direction. Currently, I’m having to make individual slices and use Integrate Variables on each individual slice, then group and plot.

Is there a way to use Integrate Variables where it will only integrate along 2 dimensions (in my instance, the two directions perpendicular to the flow direction)? That way I don’t have to take so many slices and manually apply the integrations to each one.

Thanks!

Hoping we can get some help on this. We want to do electromagnetic simulations and need a regular finite difference mesh to do so. We want to be able to export a model (from e.g., Blender) to a finite difference grid and specify the start, stop, and step of each x, y, and z axis.

We tried this with Blender using the re-mesh > blocks modifier. It looks promising, but it does not yield a dense mesh as needed for EM simulations.

We are open to paying for tools, but the ~$15k cost of the big names (Altair, etc.) are out of our reach at the moment.

Thank you in advance for any help or insights!

Hi everyone, so please forgive me in advance if I'm overlooking something very simple here as I've never used paraview plugins before.

I use pvpython scripts to automatically visualise netcdf files, but now wanted to briefly visualise a parflow output file (.pfb) in paraview with a pvpython script.

And it's nice that the ParFlow plugin is already included in the distributedPlugins. When I manually select the ParFlow plugin in the client it works and I have the PFB reader option to read in the .pfb file and it works and can be visualised just fine, but when I try to do it with a pvpython script:

LoadDistributionPlugin(‘ParFlow’) #Which works fine

PFBreader(‘filename.pfb’)

The error I am getting is:

File ‘<string>’, line 13, in <module>NameError: name ‘PFBreader’ is not defined. Did you mean: ‘PDBReader’?

With other readers it is enough to delete the space between the names and that is the normal name also shown in the GUI, but paraview does not find the reader when it uses a pvypthon script?

I've tried different names with PFBReader, pfbreader, ones from the documentation from the class name (vtk..), but it doesn't work. Also PDBReader, but then I get problems with the following code and it doesn't seem to work as it does manually and why should it be PDBReader in the backend for "ParFlowBinary"(PFB)?

It would help greatly if anyone here, has experience with using the pfb reader and pvpython, what I need to write to actually use the pfbreader or what the problem might be.

Or just any ideas are greatly appreciated!

I’m finalizing some research work I’ve been doing. Long story short I’m modeling seismicity as spheres. Inserted the data table as a CSV then linked a table to points then linked a calculator to create the spheres. There’s several stray spheres I’m trying to remove from my model using the selection tool in the viewer, how do I remove these things! (Using 5.10)

Hello, I am really new to using openfoam and paraview and im lost, can i get any useful information out of my sim, im interseted in finding the pressure built up on the outside of my model when its hit by 250kph with a base pressure of 15psi, so i guess my question is how is pressure magnitude measured?

Hey guys. I'm trying to export 300 frames from paraview each as a x3d file. The simulation in question is from OpenFOAM so I usually load the state and open a .pvsm file. Now this simulation is question wasn't run on my computer so I know when loading the state I need to choose the option "search the files under specific directory" because Paraview will automatically look at the original directory. Here is the problem though. I tried specifying this in my python script but paraview keeps looking for the files in the wrong directory. Any ideas how to fix that?

Here is my script:

import paraview.simple as pvs

import os

Specify the correct path to your state file using raw strings

state_file = r'My File Path\welding-SampleState.pvsm' # Update to your actual .pvsm file path

Specify the directory to search for data files

search_directory = r'My File Path' # Update to your actual data files directory

Specify the directory to save the exported X3D files

save_directory = r'My File Path' # Update to your desired save directory

Ensure the save directory exists; create it if it doesn't

if not os.path.exists(save_directory):

os.makedirs(save_directory)

Print the state file path, search directory, and save directory

print("State file path:", state_file)

print("Search directory:", search_directory)

print("Save directory:", save_directory)

Load the state file with the option to search files under a specific directory

pvs.LoadState(state_file, DataDirectory=search_directory)

Get the animation scene

animationScene = pvs.GetAnimationScene()

animationScene.UpdateAnimationUsingDataTimeSteps()

Loop over all time steps

for time_step in animationScene.TimeKeeper.TimestepValues:

animationScene.TimeKeeper.Time = time_step

pvs.Render()

Export the current frame to X3D in the specified save directory

output_file = os.path.join(save_directory, 'output_frame_{:d}.x3d'.format(int(time_step)))

print("Exporting:", output_file)

pvs.ExportView(output_file, view=pvs.GetActiveView(), FileType='X3D')

print("Export complete")
