Hi,
I was trying to calculate the six-component from the global Stress tensor using fix ave/euler command. The dump looks like this for two cells:
SCALARS pressure float 1
LOOKUP_TABLE default
18.087371
14.514210
-0.000000
-0.000000
-0.000000
-0.000000
17.008131
10.089578
-0.000000
-0.000000
-0.000000
-0.000000
But probably ave/euler gives the trace of the stress tensor, how can I calculate all the global six components?
Thanks,
Sounik

Maybe using the compute pressure command?
Hi, I do not know if there is any restriction with the fix ave/euler , but I compute the stress tensor using the fix mesh/surface/stress/servo . On the docs it says "A symmetric pressure tensor, stored as a 6-element vector, is also calculated by this compute" . You can find it at: https://www.cfdem.com/media/DEM/docu/compute_pressure.html . Hope this helps.
