A function space

Required Associated Types

type C: Communicator

Communicator

type T: RlstScalar

Scalar type

type Grid: Grid<T = <Self::T as RlstScalar>::Real, EntityDescriptor = ReferenceCellType> + ParallelGrid<Self::C>

The grid type

type FiniteElement: FiniteElement<T = Self::T> + Sync

The finite element type

Required Methods

fn comm(&self) -> &Self::C

Get the communicator

fn grid(&self) -> &Self::Grid

Get the grid that the element is defined on

fn element(&self, cell_type: ReferenceCellType) -> &Self::FiniteElement

Get the finite element used to define this function space

fn is_serial(&self) -> bool

Check if the function space is stored in serial

fn get_local_dof_numbers( &self, entity_dim: usize, entity_number: usize, ) -> &[usize]

Get the DOF numbers on the local process associated with the given entity

fn local_size(&self) -> usize

Get the number of DOFs associated with the local process

fn global_size(&self) -> usize

Get the number of DOFs on all processes

fn cell_dofs(&self, cell: usize) -> Option<&[usize]>

Get the local DOF numbers associated with a cell

unsafe fn cell_dofs_unchecked(&self, cell: usize) -> &[usize]

Get the local DOF numbers associated with a cell

Safety

The function uses unchecked array access

fn cell_colouring(&self) -> HashMap<ReferenceCellType, Vec<Vec<usize>>>

Compute a colouring of the cells so that no two cells that share an entity with DOFs associated with it are assigned the same colour

fn global_dof_index(&self, local_dof_index: usize) -> usize

Get the global DOF index associated with a local DOF index

fn ownership(&self, local_dof_index: usize) -> Ownership

Get ownership of a local DOF
