Method Summary

void	discretize(ShapeFunction function) Discretize the initial Shape function and initialize the moments
boolean	hasOption(java.lang.String option) Tells whether the solution implements a option
boolean	next(RunData runData) Advance the solution forward one step in time.
boolean	previous(RunData runData) Take the solution backward one step to initialize schemes with 3 time levels; not really appropriate in this context.

Constructor Detail

FEMSolution

public FEMSolution(RunData runData)

Creates a FEMSolution object.

Parameters:

runData - The run time parameters

Method Detail

next

public boolean next(RunData runData)

Advance the solution forward one step in time. The equation is set by the internal variable topic and the numerical scheme by the internal variable scheme

Specified by:

next in class Solution

Parameters:

runData - List of run parameters

Returns:

True if a scheme is implemented for that equation

See Also:

RunData

previous

public boolean previous(RunData runData)

Take the solution backward one step to initialize schemes with 3 time levels; not really appropriate in this context.

Specified by:

previous in class Solution

Parameters:

runData - List of run parameters

Returns:

False since it is not used here

See Also:

RunData

hasOption

public boolean hasOption(java.lang.String option)

Tells whether the solution implements a option

Specified by:

hasOption in class Solution

Parameters:

option - The the option to implement

Returns:

True if the option is implemented

discretize

public void discretize(ShapeFunction function)

Discretize the initial Shape function and initialize the moments

Specified by:

discretize in class Solution

Parameters:

function - The initial shape to be approximated

shiftLevels

protected void shiftLevels()

Internal function for copying new -> old
