.element_area_sum Sum of element areas.

[Atot, Ael] = element_area_sum(this, elements) returns the total area/volume of the given elements, as well as the elementwise area/volume.

Note that ‘volume’ refers to the integral of 1 over the element definition, i.e. indeed means the surface area for 2D meshes. Please multiply by the effective length if necessary.

Use elements = [] to integrate over all the elements.

.get_edge_incidence Return edges and edge incidence array.s

[edges, e2t, t2e] = get_edge_incidence(this) returns the following arrays:

• edges : size(this.Element.edge_definitions,2) x number_of_edges, with all(edges(1,:)<edges(2,:))
• e2t : 2 x number_of_edges, edges-to-elements incidence. Zeros on the second row for boundary edges.
• t2e : size(this.Element.edge_definitions,1) x number_of_elements, elements to edges incidence. Edges directionally defined according to this.Element.edge_definitions; negative values indicate edges (as defined by edges) oriented opposite to the element direction.
