Hi all,
I am trying to understand the 6 components of stress tensor computed by stress/atom.
What are the physical meaning of kinetic energy contribution, angle, dihedral and improper component of the stress tensor?
What should be the keyword listed if I want to compute the stress tensor of a particle packing (sand foundation) under the gravitational force field?
Many thanks

Hi,
Hi,
for granular simulations only the kinetic energy contribution is relevant. If you use fix ave/euler, only this contribution is counted. Also fix ave/euler adds the convective contribution which is neglected by compute stress/atom. Just look up "granular stress tensor" e.g. in sciencedirect for more info on the physics
Best wishes
