Function/Subroutine Documentation

detect_cell_with_boundary()

subroutine mod_prepare_cut_cell::detect_cell_with_boundary	(	logical, dimension(:,:,:), intent(out)	is_cut,
		class(t_shape), intent(in)	boundary_shape,
		double precision, dimension(:), intent(in)	x_u,
		double precision, dimension(:), intent(in)	y_v,
		double precision, dimension(:), intent(in)	z_w
	)

Arguments coord_x_u, coord_y_v, coord_z_w holds the coordinates of the VERTICES of the mesh.

This routine assumes that each edge of the cell is crossed at most one time.

get_cell_boundary_ends()

subroutine mod_prepare_cut_cell::get_cell_boundary_ends	(	type(t_point_list), intent(inout)	first_point,
		type(t_point_list), intent(inout)	second_point,
		type(t_node_list), intent(in)	nodes,
		class(t_shape), intent(in)	boundary_shape,
		double precision, dimension(:), intent(in)	x_u,
		double precision, dimension(:), intent(in)	y_v,
		double precision, dimension(:), intent(in)	z_w
	)

Uses the signed distance function at each boundary. bl: bottom left, br: bottom right, …

The cell is normalized. (Not sure if this is OK.)

2D only.
