DMSwarmType#

Defines the type of DMSWARM

Synopsis#

typedef enum {
  DMSWARM_BASIC = 0,
  DMSWARM_PIC
} DMSwarmType;

Values#

  • DMSWARM_BASIC - defines N entries of varied data-types which the user may register.

  • DMSWARM_PIC - suitable for particle-in-cell methods. Configured as DMSWARM_PIC, the swarm will be aware of, another DM which serves as the background mesh.

Fields specific to particle-in-cell methods are registered by default. These include spatial coordinates, a unique identifier, a cell index and an index for the owning rank. The background mesh will (by default) define the spatial decomposition of the points defined in the swarm. DMSWARM_PIC provides support for particle-in-cell operations such as defining initial point coordinates, communicating particles between sub-domains, projecting particle data fields on to the mesh.
