NAME

geo_element - element of a mesh

DESCRIPTION

Defines geometrical elements and sides as a set of vertice and edge indexes. This element is obtained after a Piola transformation from a reference element (see reference_ele‐ ment(2)). Indexes are related to arrays of edges and vertices. These arrays are included in the description of the mesh. Thus, this class is related of a given mesh instance (see geo(2)).

EXAMPLE

This is the test of geo_element: geo_element_auto<> K; K.set_name('t') ; cout << "n_vertices: " << K.size() << endl << "n_edges : " << K.n_edges() << endl << "dimension : " << K.dimension() << endl << endl; for(geo_element::size_type i = 0; i < K.size(); i++) K[i] = i*10 ; for(geo_element::size_type i = 0; i < K.n_edges(); i++) K.set_edge(i, i*10+5) ; cout << "vertices: local -> global" << endl; for (geo_element::size_type vloc = 0; vloc < K.size(); vloc++) cout << vloc << "-> " << K[vloc] << endl; cout << endl << "edges: local -> global" << endl; for (geo_element::size_type eloc = 0; eloc < K.n_edges(); eloc++) { geo_element::size_type vloc1 = subgeo_local_vertex(1, eloc, 0); geo_element::size_type vloc2 = subgeo_local_vertex(1, eloc, 1); cout << eloc << "-> " << K.edge(eloc) << endl << "local_vertex_from_edge(" << eloc << ") -> (" << vloc1 << ", " << vloc2 << ")" << endl; }
