Detailed Description

This class wraps together the CahnHilliard problem and the ones related to Navier Stokes, that is Velocity and Pressure.

The purpose of doing this is to be able to implement an inner fixed point iteration between these problems. This allows for bigger time steps.

Constructor & Destructor Documentation

template<int dim>

Initialize the subproblems.

Parameters:

tria	: The triangulation where the problems are defined.
data	: The collection of problem data needed to properly initialize each one of the subproblems
costream	: The conditional ostream used to send convergence information to.

template<int dim>

CHNSE< dim >::~CHNSE ( )

Clear data.

template<int dim>

void CHNSE< dim >::set_dt ( const double _dt )

Sets the time step in each one of the subproblems.

template<int dim>

void CHNSE< dim >::init ( )

Calls Problem::init on each one of the subproblems.

template<int dim>

Solve, via an inner fixed point iteration, the Cahn Hilliard Navier Stokes system.

Parameters:

ph_params	: The collection of AsFunction objects that CahnHilliard needs.
v_params	: The collection of AsFunction objects that Velocity needs.
p_params	: The collection of AsFunction objects that Pressure needs.
time	: The current time.
