Member Function Documentation

◆ distance()

double dolfin::Facet::distance ( const Point & point ) const

inline

Compute distance to given point.

Parameters

point (Point) The point.

Returns: double The distance to the point.

◆ exterior()

bool Facet::exterior ( ) const

Return true if facet is an exterior facet (relative to global mesh, so this function will return false for facets on partition boundaries). Facet connectivity must be initialized before calling this function.

◆ squared_distance()

double Facet::squared_distance ( const Point & point ) const

Compute squared distance to given point.
