Function Documentation

int t8_forest_leaf_face_orientation(t8_forest_t forest, const t8_locidx_t ltreeid, const t8_scheme_c *scheme, const t8_element_t *leaf, const int face)

Compute the leaf face orientation at given face in a forest.

For more information about the encoding of face orientation refer to t8_cmesh_get_face_neighbor.

Parameters:

forest – [in] The forest. Must have a valid ghost layer.
ltreeid – [in] A local tree id.
scheme – [in] The eclass scheme of the element.
leaf – [in] A leaf in tree ltreeid of forest.
face – [in] The index of the face across which the face neighbors are searched.

Returns:

Face orientation encoded as integer.
