class warp.fem.space.shape.SquareSerendipityShapeFunctions(degree, family)[source]#

Serendipity element: a tensor product space without interior nodes.

Side shape functions are usual Lagrange shape functions times a linear function in the normal direction. Corner shape functions are bilinear shape functions times a function of (x^{d-1} + y^{d-1}).

Parameters:

degree (int)
family (Polynomial)

__init__(degree, family)[source]#

Parameters:

degree (int)
