Function Documentation

int t8_element_get_corner_face(const t8_scheme_c *scheme, const t8_eclass_t tree_class, const t8_element_t *element, const int corner, const int face)

Compute the face numbers of the faces sharing an element’s corner.

Example quad: 2 x — x 3 | | | | face 1 0 x — x 1 face 2 Thus for corner = 1 the output is: face=0 : 2, face=1: 1

Parameters:

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

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

  • element – [in] The element.

  • corner – [in] A corner index for the face.

  • face – [in] A face index for corner.

Returns:

The face number of the face-th face at corner.
