Hi,
using LIGGGHTS 3.3.1, I am trying to consolidate a group of atoms in a box with mesh walls . I defined the coefficient of friction by "fix m3 all property/global coefficientFriction peratomtypepair 3 0.001 0.0 0.9 0.0 0.0 0.0 0.9 0.0 0.0 " and the wall and particle model by " pair_style gran model hertz tangential history" and "fix meshessprop all wall/gran model hertz tangential history ..." at the beginning. I ran the model up to a specific normal force and then changed the coefficient of friction by "fix m3 all property/global coefficientFriction peratomtypepair 3 0.24 0.0 0.9 0.0 0.0 0.0 0.9 0.0 0.0 ". (particles are type 1 and walls are type 2 and 3). After changing the coefficient of friction , it stops running with an error like this:
internal error in processor 2 (fix_contact_history_mesh.cpp)
Do anyone know the reason?
no problem was detected during the simulation by LIGGGHTS 2.3.8
I will be so grateful if you help me
thanks

Hi Ma,
Hi Ma,
if you can post a minimal runable example that shows the issue, I can have a quick look!
Best wishes

the problem does not exist by running the script in
Hi,
the problem does not exist by running the script in just one processor.
This seems odd because in LIGGGHTS 2.3.8 there was not such a problem.
thank you
