Hi,
I faced a weird problem in my simulation and it is that when I use "gran/hertz/history" as a pair_style my simulation work precisely, but when change the pair_style to "gran/hertz/history cohesion sjkr" my simulation does not work and it leads to the following messages repeatedly.
"touching neighbour atoms found, growing contact history"
I would appreciate it if anyone help me to solve this problem.
Sincerely,
Rasoul
