Dear Lammps Users
I am interested in simulating a mixture of spherical and non-spherical particles of finite size. Hence I compiled Lammps with granular and rigid packages.
In particular it is a mixture of spheres and rod-like particles. These rod-like particles are made by spheres (non-overlapping, just touching).
I used the two fixes as follows
fix 3 rods rigid/small molecule
fix 4 spherical nve/sphere
The first fix is to integrate the equation of motion for rod-like particles and the second one is for spherical particles.
In the data file, I assigned molecule ID as zero for spherical particles and I used the command to read the data file as given below
read_data data.sph-rod fix prop NULL Molecules
Lammps version I am using : 30 July 2016.
My question is if we use two fixes like above , does it take care of the interactions between spheres and rods ?
Please let me know your suggestions if you have performed such kind of granular simulations
