[lammps-users] A question about granular simulations.

Dear all LAMMPS users
I want to pour 2 types grain in my simulation box. but my grains have 2 size und with one density. How can I pour 2 types grains with different size in my simulation box?
I should be change the reference of my package or I can do it by changing fix insert command?
with the best regards

You could either modify the fix_insert command, or possibly
define 2 fix inserts, e.g. each having their own geometric
region to do the insertions. However, if you want to insert
2 kinds of particles in one region (pour a mixture), then you
probably need one modified fix insert.
