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.

Constructor & Destructor Documentation

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.

Member Function Documentation

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 193 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 228 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 >.
