class MultiMeshFunctionSpace

Parent class(es)

• Variable

This class represents a function space on a multimesh. It may may be created from a set of standard function spaces by repeatedly calling add(), followed by a call to build(). Note that a multimesh function space is not useful and its data structures are empty until build() has been called.

MultiMeshFunctionSpace()

Create empty multimesh function space

std::size_t dim() const

Return dimension of the multimesh function space

Returns

std::size_t

The dimension of the multimesh function space.

std::shared_ptr<const MultiMesh> multimesh() const

Return multimesh

Returns

MultiMesh

The multimesh.

std::shared_ptr<const MultiMeshDofMap> dofmap() const

Return multimesh dofmap

Returns

MultiMeshDofMap

The dofmap.

std::size_t num_parts() const

Return the number of function spaces (parts) of the multimesh function space

Returns

std::size_t

The number of function spaces (parts) of the multimesh function space.

std::shared_ptr<const FunctionSpace> part(std::size_t i) const

Return function space (part) number i

Arguments

i (std::size_t)

The part number

Returns

FunctionSpace

Function space (part) number i

std::shared_ptr<const FunctionSpace> view(std::size_t i) const

Return view of multimesh function space for part number i. This function differs from the part() function in that it does not return the original function space for a part, but rather a view of the common multimesh function space (dofs global to the collection of parts).

Arguments

i (std::size_t)

The part number

Returns

FunctionSpace

Function space (part) number i

void add(std::shared_ptr<const FunctionSpace> function_space)

Add function space (shared pointer version)

Arguments

function_space (FunctionSpace)

The function space.

void add(const FunctionSpace& function_space)

Add function space (reference version)

Arguments

function_space (FunctionSpace)

The function space.

void build()

Build multimesh function space

void build(std::shared_ptr<MultiMesh> multimesh, const std::vector<dolfin::la_index>& offsets)

Build multimesh function space. This function reuses an existing multimesh and uses offsets computed from the full function spaces on each part.
