[lammps-users] fix_rigid: richardson reference

Dear Lammps users,

I am looking over the fix_rigid code and see a function called richardson() and references to Richardson updates. Would anyone know if there a reference that goes along with this? I haven't been able to find it searing "richardson rigid body dynamics" in the literature.

Thanks,
Joyce

Richardson doesn't have anything to do with rigid bodies,
it's just a numerical means to iterate an equation to convergence.

Try Richardon on Wikipedia. It's also in the index of Numerical
Recipes a couple times. In LAMMPS, we're not interating
indefinitely, just 2 times to be more accurate.
