arguments for dump local/gran/vtk

Submitted by ninazbh on Wed, 07/12/2017 - 05:58

hello,

I am using dump local/gran/vtk command as follow to visualize forcechain in paraview:

dump forcechain all local/gran/vtk 1000 dump*.vtk

However, I get the following error:

ERROR: dump local/gran/vtk requires 6 arguments (../dump_local_gran_vtk.cpp:94)

Unfortunately, I cannot find any information about this dump style in online documentation of LIGGGHTS 3.X (The online manual). I would appreciate if anyone could tell me what arguments are needed for this dump style.

Thank you,
Nina

Hello,
You have to include the folder name where the force files will be saved, for example:
dump forcechain all local/gran/vtk 1000 /force/forcechain*.vtp cpgl
the files will be saved into a folder called force.

cpgl is a set of data that must be calculated in a previous step, for example:
compute cpgl all pair/gran/local pos vel force

Finally, You can save the files with .vtp extension. I hope this can help.
Cheers,
Carlos
