Detailed Description

template<int dim>
class Functions::PoisseuilleFlow< dim >

Laminar pipe flow in two and three dimensions. The channel stretches along the x-axis and has radius radius. The Reynolds number is used to scale the pressure properly for a Navier-Stokes problem.

Author: Guido Kanschat, 2007

◆ PoisseuilleFlow()

template<int dim>

Functions::PoisseuilleFlow< dim >::PoisseuilleFlow	(	const double	r,
		const double	Re
	)

Construct an object for the given channel radius r and the Reynolds number Re.

◆ vector_values()

template<int dim>

void Functions::PoisseuilleFlow< dim >::vector_values	(	const std::vector< Point< dim > > &	points,
		std::vector< std::vector< double > > &	values
	)		const

virtual

Values in a structure more suitable for vector valued functions. The outer vector is indexed by solution component, the inner by quadrature point.

Implements Functions::FlowFunction< dim >.

Definition at line 201 of file flow_function.cc.

◆ vector_gradients()

template<int dim>

void Functions::PoisseuilleFlow< dim >::vector_gradients	(	const std::vector< Point< dim > > &	points,
		std::vector< std::vector< Tensor< 1, dim > > > &	gradients
	)		const

virtual

Gradients in a structure more suitable for vector valued functions. The outer vector is indexed by solution component, the inner by quadrature point.

Implements Functions::FlowFunction< dim >.

Definition at line 236 of file flow_function.cc.

◆ vector_laplacians()

template<int dim>

void Functions::PoisseuilleFlow< dim >::vector_laplacians	(	const std::vector< Point< dim > > &	points,
		std::vector< std::vector< double > > &	values
	)		const

virtual

Force terms in a structure more suitable for vector valued functions. The outer vector is indexed by solution component, the inner by quadrature point.

Warning: This is not the true Laplacian, but the force term to be used as right hand side in Stokes' equations

Implements Functions::FlowFunction< dim >.
