Function Documentation

cs_mesh_cut()

void cs_mesh_cut	(	cs_mesh_t *	mesh,
		const cs_real_t	p_normals[][3],
		const cs_real_t	p_origins[][3]
	)

Cut cells with planes.

Each cell can be cut by a single plane, defined by its normal and an origin (i.e. any point in the plane). Cells whose assigned normals are null vectors are not cut.

The polygons created by the cut are added to a new group, "auto:closing_polygons".

This function should be followed by applying a joining on the group, "auto:transformed_internal_faces".

Parameters

[in,out]	mesh	mesh to cut
[in]	p_normals	array of plane_normals of size mesh->n_cells
[in]	p_origins	array of plane origins of size mesh->n_cells
