DMBoundaryConditionType#

indicates what type of boundary condition is to be imposed

Synopsis#

Values#

  • 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

Note#

The user can check whether a boundary condition is essential using (type & DM_BC_ESSENTIAL), and similarly for natural conditions (type & DM_BC_NATURAL)
