Detailed Description

template<int dim>
class aspect::Utilities::VectorFunctionFromVelocityFunctionObject< dim >

Conversion object where one can provide a function that returns a tensor for the velocity at a given point and it returns something that matches the Function interface with a number of output components equal to the number of components of the finite element in use.

Constructor & Destructor Documentation

VectorFunctionFromVelocityFunctionObject()

template<int dim>

aspect::Utilities::VectorFunctionFromVelocityFunctionObject< dim >::VectorFunctionFromVelocityFunctionObject	(	const unsigned int	n_components,
		const std::function< Tensor< 1, dim >(const Point< dim > &)> &	function_object
	)

Given a function object that takes a Point and returns a Tensor<1,dim>, convert this into an object that matches the Function<dim> interface.

Parameters

n_components	total number of components of the finite element system.
function_object	The function that will form one component of the resulting Function object.

Member Function Documentation

value()

template<int dim>

double aspect::Utilities::VectorFunctionFromVelocityFunctionObject< dim >::value ( const Point< dim > &  p, const unsigned int  component = 0  ) const

override

Return the value of the function at the given point. Returns the value the function given to the constructor produces for this point.

vector_value()

template<int dim>

void aspect::Utilities::VectorFunctionFromVelocityFunctionObject< dim >::vector_value ( const Point< dim > &  p, Vector< double > &  values  ) const

override

Return all components of a vector-valued function at a given point.

values shall have the right size beforehand, i.e. #n_components.
