DMBoundaryConditionType#
indicates what type of boundary condition is to be imposed
Synopsis#
typedef enum {
DM_BC_ESSENTIAL = 1,
DM_BC_ESSENTIAL_FIELD = 5,
DM_BC_NATURAL = 2,
DM_BC_NATURAL_FIELD = 6,
DM_BC_ESSENTIAL_BD_FIELD = 9,
DM_BC_NATURAL_RIEMANN = 10
} DMBoundaryConditionType;
Note: This flag indicates the type of function which will define the condition#
DM_BC_ESSENTIAL - A Dirichlet condition using a function of the coordinates
DM_BC_ESSENTIAL_FIELD - A Dirichlet condition using a function of the coordinates and auxiliary field data
DM_BC_ESSENTIAL_BD_FIELD - A Dirichlet condition using a function of the coordinates, facet normal, and auxiliary field data
DM_BC_NATURAL - A Neumann condition using a function of the coordinates
DM_BC_NATURAL_FIELD - A Neumann condition using a function of the coordinates and auxiliary field data
DM_BC_NATURAL_RIEMANN - A flux condition which determines the state in ghost cells
The user can check whether a boundary condition is essential using (type & DM_BC_ESSENTIAL), and similarly for natural conditions (type & DM_BC_NATURAL)
