Problem with multisphere visualization in Paraview

Submitted by nicolasoviedoc on Wed, 06/21/2017 - 16:31

Hello to all of you

I have recently simulated the multisphere example that LIGGGHTS bring in the "examples" folder. After the post process, i use Paraview (version 4.1), but when i opened the VTK file, this error appears:

ERROR: In /build/buildd/paraview-4.1.0+dfsg+1/VTK/IO/Legacy/vtkDataReader.cxx, line 1919
vtkPolyDataReader (0x3518b50): Unsupported data type: 1

I think this is because of the version of Paraview, so my questions is, what version of Paraview support multispheres?

Thanks

Nicolás.

Hi Nicolás,

one of my colleagues used multisphere with Paraview 5.something. Does this error appear only in the beginning or througout the visualisation?
I had a similar error without multiphere package. The reason for my problem were empty dump files. Paraview doesn't like these. So I usually make sure that there were particles inserted before I write the first dump file.
Hope I could help you. Keep us updated if you find a solution :)

The message shows when i click the "apply" button, and the example of LIGGGHTS charges a single particle before the first dump file, that's why this is so weird.

Anyway, i keep looking for a solution.

Thanks for your answer ;)

Nicolás.

The problem comes from the fact that the dump is empty. This is because no particles are created initially. As a fix insert/pack is used the particles will only appear after the initial time step. In order to avoid further confusion I will slightly modify this example for the next release. Thank you for reporting this issue.
