Invalid dump style & Could not find fix group ID

hello,

i am having difficulty dumping the stress on each element on a mesh.

In the link (https://www.cfdem.com/media/DEM/docu/dump.html) an example command is given:
"dump dmpAllMeshes mesh/vtk 100 mesh*.vtk stress wear"

This seems to be different to the syntax in that the group ID is missing, (dump ID group-ID style N file args), and I do in fact get the error message stating 'ERROR: Could not find fix group ID (../modify.cpp:780)'.

When I do put in a group ID 'all' to give "dump dmpAllMeshes all mesh/vtk 100 mesh*.vtk stress wear" i get a different error message stating 'ERROR: Invalid dump style (../output.cpp:634)'.

I feel like i'm just going around in circles with this. I am able to get other dump commands working but not this one. Any help would be greatly appreciated.

Thanks,
Jon

Do
"dump dmpAllMeshes all mesh/vtk 100 mesh*.vtk stress wear"
for the group "all" that encompasses all atoms.

Hi!

Thanks for that hint. There is an error within the documentation, the 'group' is missing. By default I would use 'all'.
For the second error message: 'mesh/vtk' requires vtk-support. Did you compile it with vtk?

Best wishes
Andreas

Thanks for clarifying, will look into how i've compiled the vtk. I'm use LIGGGHTS on a shared HPC so I think its an issue with the paths to vtk.
