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_element(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;
}
