int t8_element_extrude_face(const t8_scheme_c *scheme, const t8_eclass_t tree_class, const t8_element_t *face, t8_element_t *element, int root_face)

Given a boundary face inside a root tree’s face construct the element inside the root tree that has the given face as a face.

Parameters:

• scheme – [in] The scheme of the forest.

• tree_class – [in] The eclass of tree the elements are part of.

• face – [in] A face element.

• element – [inout] An allocated element. The entries will be filled with the data of the element that has face as a face and lies within the root tree.

• root_face – [in] The index of the face of the root tree in which face lies.

Returns:

The face number of the face of element that coincides with face.
