Hi everybody,
I found the following error message in liggghts version 1.4.5 as well in 1.4.4. I run a case with 209301 particles and 3 particle types on 8 cores (error message doesnt seem to depend on the number of cores). As pair style I use gran/hooke/history/stiffness 0 0. After setting up the case I get the following error:
IGGGHTS 1.4.5 based on lammps-10Mar10
Reading data file ...
orthogonal box = (-0.111 -0.111 0) to (0.111 0.111 0.039)
2 by 4 by 1 processor grid
209301 atoms
18118 atoms in group boundary
179086 atoms in group particle
Setting up run ...
ERROR on proc 1: Failed to reallocate -2146207216 bytes for array contact_history:contacthistory
6 additional processes aborted (not shown)
I ran the same case already with a older version of liggghts (version 1.10) and everything went fine. Do you have any idea what is going wrong?
Kind regards,
Fabian

At first glance, I do not
At first glance, I do not think this is a bug... I would rather guess that you have a highly overlapping particle configuration that causes this. Does this message come up before the first run starts?
Which pair style are you using?

You are right, I accidentally
You are right, I accidentally set the cutoff distance for the generation of the neighbor list too high. With a lower number it works fine. Thanks for your help.
