class CCFEMDofMap¶

Parent class(es)

GenericDofMap

This class handles the mapping of degrees of freedom for CCFEM function spaces.

CCFEMDofMap()¶: Constructor

std::size_t num_parts() const¶

Return the number dofmaps (parts) of the CCFEM dofmap

Returns

std::size_t: The number of dofmaps (parts) of the CCFEM dofmap

boost::shared_ptr<const GenericDofMap> part(std::size_t i) const¶

Return dofmap (part) number i

Returns

GenericDofMap: Dofmap (part) number i

void set_current_part(std::size_t part) const¶

Set current part. This will make the CCFEM dofmap act as a dofmap for the part of the CCFEM function space defined on the current part (mesh).

Arguments

part (std::size_t): The number of the part.

void add(boost::shared_ptr<const GenericDofMap> dofmap)¶

Add dofmap (shared pointer version)

Arguments

dofmap (GenericDofMap): The dofmap.

void add(const GenericDofMap &dofmap)¶

Add dofmap (reference version)

Arguments

dofmap (DofMap): The dofmap.

void build(const CCFEMFunctionSpace &function_space)¶: Build CCFEM dofmap

void clear()¶: Clear CCFEM dofmap

bool is_view() const¶: True if dof map is a view into another map (is a sub-dofmap)

std::size_t global_dimension() const¶: Return the dimension of the global finite element function space

std::size_t cell_dimension(std::size_t index) const¶: Return the dimension of the local finite element function space on a cell

std::size_t max_cell_dimension() const¶: Return the maximum dimension of the local finite element function space

std::size_t num_entity_dofs(std::size_t dim) const¶: Return the number of dofs for a given entity dimension

std::size_t num_facet_dofs() const¶: Return number of facet dofs

boost::shared_ptr<const Restriction> restriction() const¶: Restriction if any. If the dofmap is not restricted, a null pointer is returned.

std::pair<std::size_t, std::size_t> ownership_range() const¶: Return the ownership range (dofs in this range are owned by this process)

const boost::unordered_map<std::size_t, unsigned int> &off_process_owner() const¶: Return map from nonlocal-dofs (that appear in local dof map) to owning process

const std::vector<dolfin::la_index> &cell_dofs(std::size_t cell_index) const¶: Local-to-global mapping of dofs on a cell

void tabulate_facet_dofs(std::vector<std::size_t> &dofs, std::size_t local_facet) const¶: Tabulate local-local facet dofs

void tabulate_entity_dofs(std::vector<std::size_t> &dofs, std::size_t dim, std::size_t local_entity) const¶: Tabulate the local-to-local mapping of dofs on entity (dim, local_entity)

std::vector<dolfin::la_index> dof_to_vertex_map(const Mesh &mesh) const¶: Return a map between vertices and dofs

std::vector<std::size_t> vertex_to_dof_map(const Mesh &mesh) const¶: Return a map between vertices and dofs

void tabulate_coordinates(boost::multi_array<double, 2> &coordinates, const std::vector<double> &vertex_coordinates, const Cell &cell) const¶: Tabulate the coordinates of all dofs on a cell (UFC cell version)

std::vector<double> tabulate_all_coordinates(const Mesh &mesh) const¶: Tabulate the coordinates of all dofs owned by this process. This function is typically used by preconditioners that require the spatial coordinates of dofs, for example for re-partitioning or nullspace computations. The format for the return vector is [x0, y0, z0, x1, y1, z1, . . .].

boost::shared_ptr<GenericDofMap> copy() const¶: Create a copy of the dof map

boost::shared_ptr<GenericDofMap> create(const Mesh &new_mesh) const¶: Create a new dof map on new mesh

boost::shared_ptr<GenericDofMap> extract_sub_dofmap(const std::vector<std::size_t> &component, const Mesh &mesh) const¶: Extract sub dofmap component

boost::shared_ptr<GenericDofMap> collapse(boost::unordered_map<std::size_t, std::size_t> &collapsed_map, const Mesh &mesh) const¶: Create a “collapsed” a dofmap (collapses from a sub-dofmap view)

std::vector<dolfin::la_index> dofs() const¶: Return list of global dof indices on this process

void set(GenericVector &x, double value) const¶: Set dof entries in vector to a specified value. Parallel layout of vector must be consistent with dof map range. This function is typically used to construct the null space of a matrix operator

void set_x(GenericVector &x, double value, std::size_t component, const Mesh &mesh) const¶: Set dof entries in vector to the value*x[i], where x[i] is the spatial coordinate of the dof. Parallel layout of vector must be consistent with dof map range. This function is typically used to construct the null space of a matrix operator, e.g. rigid body rotations.

const boost::unordered_map<std::size_t, std::vector<unsigned int>> &shared_dofs() const¶: Return map from shared dofs to the processes (not including the current process) that share it.

const std::set<std::size_t> &neighbours() const¶: Return set of processes that share dofs with the this process

std::string str(bool verbose) const¶: Return informal string representation (pretty-print)
