Function Documentation

◆ cs_mesh_intersect_polyline_cell_select()

void cs_mesh_intersect_polyline_cell_select	(	void *	input,
		cs_lnum_t	n_points,
		cs_lnum_t *	n_cells,
		cs_lnum_t **	cell_ids,
		cs_real_t **	seg_c_len
	)

Select cells cut by a line composed of segments.

This selection function may be used as an elements selection function for postprocessing.

In this case, the input points to a real array containing the segment's start and end coordinates.

Note: the input pointer must point to valid data when this selection function is called, so either:

that value or structure should not be temporary (i.e. local);
post-processing output must be ensured using cs_post_write_meshes() with a fixed-mesh writer before the data pointed to goes out of scope;

The caller is responsible for freeing the returned cell_ids array. When passed to postprocessing mesh or probe set definition functions, this is handled automatically.

Parameters

[in]	input	pointer to segments starts and ends: [x0, y0, z0, x1, y1, z1]
[in]	n_points	number of vertices in the polyline
[out]	n_cells	number of selected cells
[out]	cell_ids	array of selected cell ids (0 to n-1 numbering)
[out]	seg_c_len	array of length of the segment in the selected cells

◆ cs_mesh_intersect_segment_cell_select()

		cs_lnum_t *	n_cells,
		cs_lnum_t **	cell_ids
	)

Select cells cut by a given segment.
