Method Detail

prepare

public void prepare(Problem problem)
             throws SolverException

Description copied from class: DifferenceScheme

Contains preparatory steps to ensure smooth running of the solver.This includes creating a DiscretePulseobject and adjusting the grid of this scheme to match the DiscretePulsecreated for this problem Finally, a heating curve is cleared from the previously calculated values.

All subclasses of DifferenceScheme should override and explicitly call this superclass method where appropriate.

Overrides:

prepare in class ImplicitScheme

Parameters:

problem - the heat problem to be solved

Throws:

SolverException

solve

public void solve(NonlinearProblem problem)
           throws SolverException

Description copied from interface: Solver

Calculates the solution of the t and stores it in the respective HeatingCurve.

Specified by:

solve in interface Solver<NonlinearProblem>

Parameters:

problem - - an accepted instance of T

Throws:

SolverException

copy

public DifferenceScheme copy()

Description copied from class: DifferenceScheme

Creates a DifferenceScheme, which is an exact copy of this object.

Specified by:

copy in class DifferenceScheme

Returns:

an exact copy of this DifferenceScheme.

domain

public Class<? extends Problem>[] domain()

Description copied from class: DifferenceScheme

Retrieves all problem statements that can be solved with this implementation of the difference scheme.

Specified by:

domain in class DifferenceScheme

Returns:

an array containing subclasses of the Problem class which can be used as input for this difference scheme.

getNonlinearPrecision

public NumericProperty getNonlinearPrecision()

setNonlinearPrecision

public void setNonlinearPrecision(NumericProperty nonlinearPrecision)

listedKeywords

public Set<NumericPropertyKeyword> listedKeywords()

Description copied from class: DifferenceScheme

The superclass only lists the TIME_LIMIT property.

Overrides:

listedKeywords in class DifferenceScheme

Returns:

a set of NumericPropertyKeyword instances, which have been explicitly marked as a listed parameter for this PropertyHolder.

set

public void set(NumericPropertyKeyword type,
                NumericProperty property)

Description copied from class: Accessible

An abstract method, which must be overriden to gain access over setting the values of all relevant (selected by the programmer) NumericProperties in subclasses of Accessible. Typically this involves a switch statement that goes through the different options for the type and invokes different set(...) methods to update the matching NumericProperty with property.

Overrides:

set in class DifferenceScheme

Parameters:

type - the type, which must be equal by definition to property.getType().

property - the property, which contains new information.

timeStep

public void timeStep(int m)
              throws SolverException

Description copied from class: ImplicitScheme

Calculates the solution at the boundaries using the boundary conditions specific to the problem statement and runs the tridiagonal matrix algorithm to evaluate solution at the intermediate grid points.

Overrides:

timeStep in class ImplicitScheme

Parameters:

m - the time step

Throws:

SolverException - if the calculation failed

iteration

public void iteration(int m)
               throws SolverException

Description copied from interface: FixedPointIterations

Performs an iteration at time m

Specified by:

iteration in interface FixedPointIterations

Parameters:

m - time step

Throws:

SolverException - if the calculation failed

evalRightBoundary

public double evalRightBoundary(double alphaN,
                                double betaN)

Specified by:

firstBeta

public double firstBeta()

Specified by:

firstBeta in class ImplicitScheme
