FormDiagram.dual_diagram

FormDiagram.dual_diagram(cls)[source]

Construct the dual of the FormDiagram.

Parameters

cls (Mesh) – The type of the dual.

Returns

Mesh – The dual as an instance of type cls.

Notes

Construction of the dual diagram is based on the faces around the inner, free vertices of the form diagram. This means not only the vertices on the boundary are ignored, but also the vertices that are anchored.
