/* ERROR/WARNING messages:
|
|
|
|
E: Pair style granular with history requires atoms have IDs
|
|
|
|
Atoms in the simulation do not have IDs, so history effects
|
|
cannot be tracked by the granular pair potential.
|
|
|
|
E: Too many touching neighbors - boost MAXTOUCH
|
|
|
|
A granular simulation has too many neighbors touching one atom. The
|
|
MAXTOUCH parameter in fix_shear_history.cpp must be set larger and
|
|
LAMMPS must be re-built.
