Function/Subroutine Documentation

count_nonzeros_in_linear_system_without_overlapping()

pure subroutine type_face_ls_map::count_nonzeros_in_linear_system_without_overlapping	(	type(t_face_ls_map), intent(inout)	ls_map,
		type(t_face_stencil), intent(in)	stencil
	)

Parameters

[in,out]	ls_map	linear system mapping.
[in]	stencil	discretization stencil.

global_face_local_lexicographic_indexing()

subroutine type_face_ls_map::global_face_local_lexicographic_indexing

(

type(t_face_ls_map), intent(inout)

ls_map

)

The global index is computed without overlapping.

The global index is set to UNUSED_INDEX if a node is not used in the linear system.

Parameters

[in,out]

ls_map

face-based linear system mapping.

initialize_face_ls_map()

subroutine, public type_face_ls_map::initialize_face_ls_map	(	type(t_face_ls_map), intent(inout)	ls_map,
		type(t_face_stencil), intent(in)	stencil,
		logical, intent(in)	has_ghost_boundary_cells
	)

Parameters

[in,out]	ls_map	face-based linear system mapping.
[in]	stencil	discretization stencil.
[in]	has_ghost_boundary_cells	use ghost boundary cells in the discretization?
