A Facet is a MeshEntity of topological codimension 1.

Constructor

distance()

Compute distance to given point.

Arguments

point (Point)

The point.

Returns

float

The distance to the point.

exterior()

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.

normal()

Overloaded versions

• normal(i)

  Compute component i of the normal to the facet

• normal()

  Compute normal to the facet

squared_distance()

Compute squared distance to given point.

Arguments

point (Point)

The point.

Returns

float

The squared distance to the point.
