Hi,
I am using a cloud server for CFD simulations using OpenFOAM 7.0 and then ParaView 5.6.0 for graphical post-processing of the results. I am running a client-host setup of ParaView and finally managed to load the OpenFOAM-reader for ParaView. I am using the OpenFOAM plugin reader supplied the OpenFOAM package, since I am working with Lagrangian particles, that the OF-reader can read. The native OF-reader in ParaView does not recognize the particles and I have to convert to VTK for it to read.
The OF-plugins are now loaded and I am able to read the files, but as soon as my particle count get too high, ParaView crashes with the following error:
> ERROR: In /opt/OpenFOAM/ThirdParty-7/ParaView-5.6.0/VTK/Rendering/OpenGL2/vtkOpenGLRenderWindow.cxx, line 1931
> vtkOSOpenGLRenderWindow (0x56339984a610): Hardware does not support the number of textures defined.
I am using the following command to launch ParaView and the OpenFOAM plugins:
Single core:
> LD\_PRELOAD=/opt/OpenFOAM/ThirdParty-7/platforms/linux64Gcc/ParaView-5.6.0/lib/libvtkpqCore-pv5.6.so.1 pvserver --force-offscreen-rendering
Parallel:
> mpirun -x LD\_PRELOAD=/opt/OpenFOAM/ThirdParty-7/platforms/linux64Gcc/ParaView-5.6.0/lib/libvtkpqCore-pv5.6.so.1 -np 4 pvserver --force-offscreen-rendering
This occurs both when ParaView is launced using MPI and when launched using a single CPU.
Any ideas on how to fix this issue? Or where to look for errors?
Best regards
Kasper.

Does the errors occurs if you do not show the particles at all ? or show them in a spreadsheet ?

Hi again,
Thanks for the quick reply.
There is no error if the particles is not displayed. Then the entire dataset is loaded from 0 to end.
If I display the particles in a spreadsheet, I get a different error:
> ERROR: In /opt/OpenFOAM/ThirdParty-7/ParaView-5.6.0/VTK/Parallel/Core/vtkSocketCommunicator.cxx, line 808

How many particle causes problems ?
Could you screenshot your information tab ?
Could you reducing the size of your dataset first, using MaskPoint filter for example ?

I can display ~220,000 particles and then I get the “Hardware does not support the number of textures defined” error.
I’ve uploaded a snapshot of the information tab before the error.
Filtering using Mask Point is an option that works! I was not aware of that. For this case I think that will be the best solution, since I don’t need to show more than 50% of the particles to give an overall view.

Hmm. For starters I was only interested in the particles suspended in the flow, but it seems I’m also not able to display the computational mesh along with the same number of particles.
I can display the mesh, consisting of 12 million cells, but then I cannot show any particles along with the mesh. I get the same hardware error.

Could you try showing them in Point Gaussian or 3D Glyphs Representation mode ?

It doesn’t seem to matter whether I display them as Surface, Point, Point Gaussian or 3D Glyphs. Same hardware error when exceeding the same threshold.
