Region styles :h3
|
|
|
|
Classes that define geometric regions are derived from the Region
|
|
class. Regions are used elsewhere in LAMMPS to group atoms, delete
|
|
atoms to create a void, insert atoms in a specified region, etc. New
|
|
styles can be created to add new region shapes to LAMMPS.
|
|
|
|
Region_sphere.cpp is an example of a spherical region.
|
|
|
|
Here is a brief description of methods you define in your new derived
|
|
class. See region.h for details.
|
|
|
|
inside: determine whether a point is in the region
|
|
surface_interior: determine if a point is within a cutoff distance inside of surc
|
|
surface_exterior: determine if a point is within a cutoff distance outside of surf
|
|
shape_update : change region shape if set by time-dependent variable :tb(s=:)
