void t8_element_get_boundary_face(const t8_scheme_c *scheme, const t8_eclass_t tree_class, const t8_element_t *element, const int face, t8_element_t *boundary)

Construct the boundary element at a specific face.

Parameters:
  • scheme[in] The scheme of the forest.

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

  • element[in] The input element.

  • face[in] The index of the face of which to construct the boundary element.

  • boundary[inout] An allocated element of dimension of element minus 1. The entries will be filled with the entries of the face of element. If element is of class T8_ECLASS_VERTEX, then boundary must be NULL and will not be modified.
