Hi,
I am trying to use lammps srd. I have a polymer (beads + fene bonds) and srd particles. Their initial positions and velocities are read from an input file. When I run the code with the the srd fix, I get the following error:
Big particle in fix srd cannot be point particle
Looking at the provided example in.srd.mixture, I notice that atom_style is set to sphere. So I do this in my input file and set the diameter to 1.0, but then I get an error because this conflicts with the statement “atom_style angle” that I also have for a bead-spring polymer (cannot set the diameter to 1.0 with it). How can I tell lammps that I have a bead-spring polymer with srd particles?

you can try combining the properties of atom style sphere and atom style
angle using atom style hybrid.
