I looked in the manual, but I couldnt find reference to this;
+ Fixed a small glitch in the new "output" option of the dump mesh/VTK command. Thanks to Philippe Seil (JKU) and Christian Richter (OVGU) for noting this.
I would like to try out this new feature, but am not sure how to set it up. Maybe the chute_weat example could be updated with this new option?!?! Or someone could explain where I can find documentation on this.

OK, thanks I found it.
I modified the dump mesk/vtk line in the chute_wear example to read;
dump dumpstress all mesh/gran/VTK 200 post/dump*.vtk output interpolate stress wear cad
The interpolated results are very nice!

Help!!!Can anyone explain how to use the mesh/vtk??
I am relatively new to LIGGGHTS. Any help is appreciated!
I tried to use the dump mesh/vtk but I got warnings. Below is my code
dump dumpstress all mesh/gran/VTK 400000 post/wall_*.vtk id vel stress
All the stress values I got were zero.
This is the warning I got
WARNING: Trying to dump stress for mesh which does not calculate stress, will dump '0' instead (../dump_mesh_vtk.cpp:438)

Your walls are not defined as
Your walls are not defined as style fix mesh/surface/stress but probably only mesh/surface.

Thank you! I fixed that issue
Thank you! I fixed that issue. Now I get output in a VTK file using this code.
dump dumpstress all mesh/gran/VTK 400000 post/wall_*.vtk id vel stress
My problem is I cannot make sense of the numbers in the file. There are too many instead of just id velocity and stress. Could anyone point me to get a clear idea of outputs? All I need is to see how much stress is on the wall in x, y and z directions and the velocities of the walls.
