Hi Christoph,
I am dumping force on base (mesh CAD) due to granular packing in cylinder, Base is moving downward. Practically the weight ( hence force along z-axis) felt by base should be constant during course of time but is it changing linearly. I am attaching the file herewith. Commands in the script are given as under:

...
fix cad2 all mesh/gran/stressanalysis base.stl 1 0.01 5. 5. 10 0. 0. 0.
...
fix movecad all move/mesh/gran linear 0. 0.0 -0.00082 cad2
....
dump dumpstl2 all mesh/gran/VTK 50 post/cad2/dump*.vtk stress cad2
fix baseforce all ave/time 50 2 100 f_cad2[1] f_cad2[2] f_cad2[3] file baseforce.txt
....
Thanks,
Ram

For me this works prefectly fine with both 1.1.10 and 1.2beta - there is probably another issue in your setup

Hi,
I am attaching my script file, but I can not find anything which can make such changes. I am using 1.1.9 version.
Best,
Ram
