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
