double t8_forest_element_face_area(t8_forest_t forest, t8_locidx_t ltreeid, const t8_element_t *element, int face)

Compute the area of an element’s face if a geometry for this tree is registered in the forest’s cmesh.

Currently implemented for 2D elements only. This is only an approximation.

Parameters:

  • forest – [in] The forest.

  • ltreeid – [in] The forest local id of the tree in which the element is.

  • element – [in] The element.

  • face – [in] A face of element.
