Hi,
I was going trough the LIGGGHTS examples and had a problem after simulations 'cohesion' and 'insert stream'. I tried opening the post-files with ParaView 5.4.0-RC2 but the programm couldn't find the right reader for the post-dump files.
Apparently the dump-files are saved as dump_xxxx.cohesion and dump_xxxx.stream. (xxxx as a number like 8000)
What should i do to be able to view the results on ParaVew?
Thanks

What is the dump command
Hello,
Are you writing vtk files? You may have to convert the output to vtk using the lpp program.

Here are the dump commands:
Hi,
dump dmp all custom 800 post/dump*.stream id type type x y z ix iy iz vx vy vz fx fy fz omegax omegay omegaz radius
dump dmp all custom 800 post/dump*.cohesion id type type x y z ix iy iz vx vy vz fx fy fz omegax omegay omegaz radius
I also tried typing ".vtk" instead of ".stream" (and ".cohesion") - After that i could run the simulation on ParaView -technically- but it wasn't the right way to view it for sure. Only saw some series of particles on a line that had almost nothing to with the simulation itself.
Thank you

Current commands
The way the commands are currently, your files are dumped in a text format. If you compiled with vtk enabled, you can use the command
Custom/vtk. This would output your files in vtk format. If you did not enabled vtk when you compiled, you either need to convert your files using lpp,
or use the paraview reader. https://www.cfdem.com/post-processing-liggghtsr-simulations
