I need to look at the packing of spherical and plate-like rigid particles. I’m confused by this statement on the body particle how to page (https://docs.lammps.org/Howto_body.html)
You should not use body particles to model a rigid body made of simpler particles (e.g. point, sphere, ellipsoid, line segment, triangular particles), if the interaction between pairs of rigid bodies is just the summation of pairwise interactions between the simpler particles. LAMMPS already supports this kind of model via the fix rigid command.
What would be the LAMMPS best practice for modeling a mixture of spherical, short fiber and plate packing?
I suspect fix rigid would be the most flexible in defining the overall particle shape?
Thanks for the help,
