Detailed Description

template<dolfinx::scalar T>
class dolfinx::fem::Constant< T >

Constant (in space) value which can be attached to a Form.

Constants may be scalar (rank 0), vector (rank 1), or tensor-valued.

Template Parameters

T	Scalar type of the Constant.

Constructor & Destructor Documentation

Constant ( value_type c )

inlineexplicit

Create a rank-0 (scalar-valued) constant.

Parameters

[in] c Value of the constant.

Constant ( std::span< const value_type > c )

inlineexplicit

Create a rank-1 (vector-valued) constant.

Parameters

[in] c Value of the constant.

Constant	(	std::span< const value_type >	c,
		std::span< const std::size_t >	shape )

inline

Create a rank-d constant.

Parameters

[in]	c	Value of the Constant (row-majors storage)
[in]	shape	Shape of the Constant
