I am trying to create various geometries, like Y shape with different angles or X shape. Is it possible to create that using fix wall/lj126, is there a way to limit the length of a fix wall/lj126 and change its angle?
From reading the manual it seem it will only work if the wall is attached to a specific region, right?
If not, what command should I look to use to specify a specific region or can I use python to define the region and feed it to LAMMPS, any guides on how to do that?
