I want to create a cylinder wall and apply periodic boundary conditions along the axis of the cylinder. It seems there aren’t commands about wall in LAMMPS. I may create it with many partices in the x,y boundies. but if I want to use steele potential between wall and other particles, How to deal with? would some people like to give some advice.Thanks in advance.
steele potential(see inclosure)
sigma_wf is fluid molecular and wall interaction parameters, and R-r is distance between them.
