Class xlifepp::Quadrangle#

class Quadrangle : public xlifepp::Polygon #

definition of a quadrangular geometry in R^3

Quadrangle constructors are based on a key-value system. Here are the available keys:

_v1, _v2, _v3, _v4: to define the vertices of the Quadrangle, counterclockwise oriented
_nnodes: to define the number of nodes on each edge of the Quadrangle
_hsteps: to define the local mesh steps on the vertices of the Quadrangle
_domain_name: to define the domain name
_side_names/_edge_names: to define the side names
_vertex_names: to define the side of side names
_varnames: to define the variable names for print purpose
