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(std::shared_ptr<const MultiMesh> multimesh)¶: Create multimesh function space on multimesh (shared pointer version)

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

Arguments

function_space (FunctionSpace): The function space.

void build()¶: Build multimesh function space

void build(const std::vector<dolfin::la_index> &offsets)¶: Build multimesh function space. This function uses offsets computed from the full function spaces on each part.
