class MultiMeshFunction¶

Parent class(es)

Variable

This class represents a function on a cut and composite finite element function space (MultiMesh) defined on one or more possibly intersecting meshes.

MultiMeshFunction()¶: Constructor

explicit MultiMeshFunction(std::shared_ptr<const MultiMeshFunctionSpace> V)¶

Create MultiMesh function on given MultiMesh function space

Arguments

V (MultiMeshFunctionSpace): The MultiMesh function space.

MultiMeshFunction(std::shared_ptr<const MultiMeshFunctionSpace> V, std::shared_ptr<GenericVector> x)¶

Create MultiMesh function on given MultiMesh function space with a given vector (shared data)

Warning: This constructor is intended for internal library use only

Arguments

V (MultiMeshFunctionSpace): The multimesh function space.
x (GenericVector): The vector.

void assign_part(std::size_t a, const Function &v)¶

Assign Function to part of a mesh

Arguments

a (int): Part mesh assigned to
V (Function): The vector

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

Return function (part) number i

Returns

Function: Function (part) number i

std::shared_ptr<const Function> part(std::size_t i, bool deepcopy) const¶

Return a (deepcopy) function (part) number i

Returns

Function: Function (part) number i bool deepcopy flag

std::shared_ptr<GenericVector> vector()¶

Return vector of expansion coefficients (non-const version)

Returns

GenericVector: The vector of expansion coefficients.

std::shared_ptr<const GenericVector> vector() const¶

Returns

GenericVector: The vector of expansion coefficients (const).

std::shared_ptr<const MultiMeshFunctionSpace> function_space() const¶

Return shared pointer to multi mesh function space

Returns

MultiMeshFunctionSpace: Return the shared pointer.

void restrict(double *w, const FiniteElement &element, std::size_t part, const Cell &dolfin_cell, const double *coordinate_dofs, const ufc::cell &ufc_cell) const¶

Arguments

w (list of doubles): Expansion coefficients.
element (FiniteElement): The element.
part (std::size_t): The mesh part
dolfin_cell (Cell): The cell.
ufc_cell (ufc::cell).: The ufc::cell.

void eval(Array<double> &values, const Array<double> &x, std::size_t part, const ufc::cell &cell) const¶

Evaluate at given point in given cell in given part

Arguments

values (Array <double>): The values at the point.
x (Array <double>): The coordinates of the point.
cell (ufc::cell): The cell which contains the given point.
