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

Member Function Documentation

template<int dim>

virtual 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 >.

template<int dim>

virtual 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 >.

template<int dim>

virtual 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.
