Description
|
|
"""""""""""
|
|
|
|
Enables AtC to base the region for internal atoms to be an element
|
|
set. If no ghost atoms are used, all the AtC atoms must be constrained
|
|
to remain in this element set by the user, e.g., with walls. If boundary
|
|
atoms are used in conjunction with Eulerian atom maps AtC will partition
|
|
all atoms of a boundary or internal type to be of type internal if they
|
|
are in the internal region or to be of type boundary otherwise.
|
|
|
|
Restrictions
|
|
""""""""""""
|
|
|
|
If boundary atoms are used in conjunction with Eulerian atom maps, the
|
|
Eulerian reset frequency must be an integer multiple of the Lammps
|
|
reneighbor frequency.
