The radial and azimuthal component of the stress tensor

Hi everyone,

I want to calculate the normal ( P_N ) and tangential ( P_T ) pressures in a nanodroplet using the Stillinger-Weber potential.

I initially considered using compute stress/spherical, but I see that it only accounts for pairwise interactions and does not include many-body interactions, such as the three-body forces in SW.

Given this restriction, does anyone have experience or suggestions on how to properly compute P_N and P_T in LAMMPS for a many-body potential?

Thanks in advance!
