VectorFunctionSpace

class dolfin.functions.functionspace.VectorFunctionSpace(mesh, family, degree, dim=None, form_degree=None, constrained_domain=None, restriction=None)

Bases: dolfin.functions.functionspace.MixedFunctionSpace

VectorFunctionSpace represents a vector-valued finite element function space.

Create vector-valued finite element function space.

Use VectorFunctionSpace if the unknown is a vector field, instead of a FunctionSpace object for scalar fields.

Arguments

mesh (Mesh)

the mesh

family (string)

a string specifying the element family, see FunctionSpace for alternatives.

degree (int)

the (polynomial) degree of the element.

dim (int)

an optional argument specifying the number of components.

form_degree (int)

an optional argument specifying the degree of the k-form (used for FEEC notation)

If the dim argument is not provided, the dimension will be deduced from the dimension of the mesh.

Example of usage

V = VectorFunctionSpace(mesh, "CG", 1)
