class final

Represents a Dirichlet boundary condition on a ShapeFunction object.

Template parameters
FES	Type of finite element space
ValueDerived	Type of value

When utilized in a Problem construction, it will impose the Dirichlet condition

on the subset of the boundary .

Base classes

template<class Scalar> class DirichletBCBase<FormLanguage::Traits<FES>::ScalarType>: Abstract base class for a Dirichlet boundary condition.

using OperandType = TrialFunction<FESType>: Operand type.
using ScalarType = typename FormLanguage::Traits<FESType>::ScalarType: Scalar type.
using ValueType = FunctionBase<ValueDerived>: Value type.
using Parent = DirichletBCBase<ScalarType>: Parent class.

DirichletBC(const OperandType& u, const ValueType& v): Constructs the object given the Operand and Value.
DirichletBC(const DirichletBC& other): Copy constructor.
DirichletBC(DirichletBC&& other): Move constructor.

auto on(Geometry::Attribute bdrAtr) -> DirichletBC& constexpr: Specifies the region of the boundary over which the condition will be imposed.
auto on(const FlatSet<Geometry::Attribute>& bdrAttrs) -> DirichletBC& constexpr: Specifies the regions of the boundary over which the condition will be imposed.
auto getAttributes() const -> const FlatSet<Geometry::Attribute>& constexpr
void assemble() override: Computes the indices of the degrees of freedoms associated to the boundary region.
auto getOperand() const -> const OperandType& override: Gets the associated operand.
auto getValue() const -> const ValueType& override: Gets the associated value.
auto getDOFs() const -> const DOFs& override: Gets the global degree of freedom map.
auto copy() const -> DirichletBC* override noexcept: Copies the object and returns a non-owning pointer to the copied object.

Constructs the object given the Operand and Value.

Parameters
u in	ShapeFunction object
v in	Value object

Specifies the regions of the boundary over which the condition will be imposed.

Parameters
bdrAttrs in	Attributes associated to the boundary regions

Returns	Attributes over which the boundary condition is imposed.

Computes the indices of the degrees of freedoms associated to the boundary region.

This will compute the degrees of freedom over the incidence set

If the set of specified attributes is empty, this will compute the degrees of freedom over the boundary, in which case the incidence set

is also required.

Copies the object and returns a non-owning pointer to the copied object.

Returns	Non-owning pointer to the copied object.
