11.12. Region styles
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 surface|
|surface_exterior||determine if a point is within a cutoff distance outside of surface|
|shape_update||change region shape if set by time-dependent variable|
