Detailed Description

The mesh object is defined here.

The mesh object is intended for interfacing from and to other codes. It can be conforming or adaptive, and replicated or distributed in parallel. On input to the creation of a forest, it provides the conforming mesh of coarse elements that are the roots of the tree-based subdivision. The coarse input mesh must be conforming (have no hanging nodes). On output this mesh contains the connectivity of a mesh that has possibly been adaptively refined (has hanging nodes), including information on remote neighbors.

Function Documentation

t8_mesh_get_element_class()

t8_locidx_t t8_mesh_get_element_class	(	t8_mesh_t *	mesh,
		t8_locidx_t	locid
	)

Parameters

[in]

locid

The local number can specify a point of any dimension that is locally relevant. The points are ordered in reverse to the element classes in t8_eclass_t. The local index is cumulative in this order.

t8_mesh_get_element_support()

void t8_mesh_get_element_support	(	t8_mesh_t *	mesh,
		t8_locidx_t	locid,
		int *	length_support,
		t8_locidx_t *	elemid,
		int *	orientation
	)

Parameters

[in,out]

length_support

t8_mesh_set_partition()

void t8_mesh_set_partition	(	t8_mesh_t *	mesh,
		int	enable
	)

Determine whether we partition in t8_mesh_build.

Default true.
