Dear Lammps users:
I am working with 2D grains in lammps. I have the vertices and the end-points of a particular polygon-shaped grain. I want to define a region with the shape of this polygon and then create atoms to generate this grain. What I am now doing is dividing the polygon into small squares and then using their dimensions in the region block command. However, this process takes too long to generate a large grain. Do you guys have any ideas on how to make this process faster? Also, is there any command in lammps that can generate polygon regions?
I know this is more of a preprocessing problem if lammps do not have any polygon region command. Still your input will be much appreciated.
