I am trying to simulate particle deposition on a surface using LIGGGHTS 2.3.8. My input code is similar to the one used by ThomasR (above) and includes sjkr cohesion model in both wall/gran/hertz/history and pair_style with value of Cohesion energy density of polymers (around 500 J/mL). But I am not able to observe cohesion among particles and between particles and walls. It would be great if someone who has modeled cohesion could tell me what's wrong with my approach. Thanks in advance !

Hi ArvindP!

First of all: Your value for the cohesion energy density seems reasonable. Nevertheless, did you try higher values?

Further I really recommend to use the latest version of LIGGGHTS.
