Member Function Documentation

beginCellIteration()

template<class LinkedCell, unsigned int dim>

void coupling::cellmappings::ComputeMomentumMapping< LinkedCell, dim >::beginCellIteration ( )

inline

sets the mean velocity, momentum and the particle counter to zero, before the iteration process begins.

endCellIteration()

template<class LinkedCell, unsigned int dim>

void coupling::cellmappings::ComputeMomentumMapping< LinkedCell, dim >::endCellIteration ( )

inline

computes the mean velocity, momentum in a linked cell, by dividing and multiplying the summation of the velocities computed in handleCell(...) over the number if particle and in particle mass respectively.

getMeanVelocity()

template<class LinkedCell, unsigned int dim>

tarch::la::Vector< dim, double > coupling::cellmappings::ComputeMomentumMapping< LinkedCell, dim >::getMeanVelocity ( ) const

inline

returns the mean velocity inside a linked cell

Returns

_meanVelocity

getMomentum()

template<class LinkedCell, unsigned int dim>

tarch::la::Vector< dim, double > coupling::cellmappings::ComputeMomentumMapping< LinkedCell, dim >::getMomentum ( ) const

inline

returns the momentum inside a linked cell

Returns

_momentum

handleCell()

template<class LinkedCell, unsigned int dim>

void coupling::cellmappings::ComputeMomentumMapping< LinkedCell, dim >::handleCell ( LinkedCell & cell )

inline

counts the molecules inside a linked cell and sums up the of the velocity of all particles inside the cell and saves it as momentum.

Parameters

cell
