warp.fem.BasisSpace#

class warp.fem.BasisSpace(topology)[source]#

Interface class for defining shape functions over a geometry.

A basis space is a component of a function space, and is responsible for defining the node positions and their weights over individual elements of the geometry. The connectivity pattern between elements of geometry is defined by the SpaceTopology. The actual valuation of the space is defined by the FunctionSpace, allowing to reuse a single basis space for multiple value types (e.g, scalar, vector, or tensor).

Parameters:: topology (SpaceTopology)

Parameters:: topology (SpaceTopology)
