problem with running in LIGGGHTS 3.3.1

Submitted by ma on Tue, 04/05/2016 - 06:59

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
ma

Hi Ma,

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

Best wishes
