Collaboration diagram for xlifepp::Ellipse:

definition of an elliptic geometry in R^3 (surface)

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

_center: to define the center of the Ellipse
_v1, _v2: to define apogees of the Ellipse
_xlength, _ylength: to define axis lengths of the Ellipse
_xradius, _yradius: to define semi-axis lengths of the Ellipse
_angle1, _angle2: to define an elliptic sector from a pair of angles. The angular origin is determined by _v1
_type: indicator to fit curved boundaries (default) or not which gives flat (or plane) boundaries
_nnodes: to define the number of nodes on the edges of the Ellipse
_hsteps: to define the local mesh steps on build points of the Ellipse
_domain_name: to define the domain name
_side_names: to define the side names
_varnames: to define the variable names for print purpose
