ConvectionOperator Struct Template Reference

Operator for evaluation of convection terms (standard) or (conservative). The advection velocity must be given as nodal values. More...

#include <Operators.hpp>

Inheritance diagram for ConvectionOperator::

List of all members.

Public Methods
	ConvectionOperator ()
	Default constructor.
void	ApplyConservativeWENO (I *X, I *Result)
	Evaluation of conservative form using 5th order WENO scheme, strongly recommended !!!
virtual void	Apply (I *X, I *Result)
	Evaluation of non-conservative form using Petrov-Galerkin discertization.
void	ApplyFD (I *X, I *Result)
	Evaluation of non-conservative form using finite differences.
void	ApplyConservative (I *X, I *Result)
	Evaluation of conservative form using Petrov-Galerkin discertization.
void	ApplyConservativeFD (I *X, I *Result)
	Evaluation of conservative form using finite differences.
virtual void	Preconditioner (I *X, I *Result)
	if one wants to solve an operator equation with this operator, one can provide a preconditioner.
virtual void	InversePreconditioner (I *X, I *Result)
	the BiCGStab2 solver also needs the inverse operation.
virtual double	DiagonalEntry (int *level, Wavelets *W)
	often the DiagonalEntry is needed for preconditioners.
virtual void	NotUsing (I *X)
	the solvers check whether the temporary data used by them is also used for the evaluation of the operator; this is avoids wrong numerical results.
Public Attributes
I*	U [DIM]
	Nodal values of velocity components.
I*	Tmp
	Auxiliary data.
I *	Tmp1
	Auxiliary data.
