add_face_bc_normal()

subroutine mod_add_face_bc_normal::add_face_bc_normal	(	double precision, dimension(:), intent(inout)	matrix,
		double precision, dimension(:), intent(inout)	rhs,
		type(t_boundary_condition_face), intent(in)	boundary_condition,
		type(t_face_stencil), intent(in)	face_equation_stencil,
		type(t_face_ls_map), intent(in)	face_equation_ls_map,
		logical, intent(in)	face_equation_has_ghost_boundary_cells )

• faces are located on the boundaries

add_face_bc_tangent()

subroutine mod_add_face_bc_tangent::add_face_bc_tangent	(	double precision, dimension(:), intent(inout)	matrix,
		double precision, dimension(:), intent(inout)	rhs,
		type(t_boundary_condition_face), intent(inout)	boundary_condition,
		type(t_face_stencil), intent(in)	face_equation_stencil,
		type(t_face_ls_map), intent(in)	face_equation_ls_map )

• faces are not located on the boundaries
• extra ghost faces are used
• centered scheme is used for Dirichlet or Neumann boundary conditions on the first range of ghost cells
• second order extrapolation is used on the second range of ghost cells (if stencil_type = 2)
