Dear LAMMPS Developers
I am using gra/hook pair potential which has both normal and tangential forces:
pair_style gran/hooke 1 1 1 1 0.5 1
My question is that if I use:
compute 2 all pair/local dist force fx fy fz cutoff radius
Does force = magnitude of vectorial sum of normal and tangential forces
then DO fx fy fz include sum of components of normal and tangential forces?
Or they are just components of the normal forces?
If they are just normal forces should I use this to dump components of the tangential force:
compute 2 all pair/local dist force fx fy fz p1 p2 p3 cutoff radius
In advance, I appreciate your kind response.
