class dolfin.cpp.function.MultiMeshSubSpace(*args)

Bases: dolfin.cpp.function.MultiMeshFunctionSpace

This class represents a subspace (component) of a multimesh function space. The subspace is specified by an array of indices. For example, the array [3, 0, 2] specifies subspace 2 of subspace 0 of subspace 3. A typical example is the function space W = V x P for Stokes. Here, V = W[0] is the subspace for the velocity component and P = W[1] is the subspace for the pressure component. Furthermore, W[0][0] = V[0] is the first component of the velocity space etc.

Create subspace for given component (n levels)
