SkewAdvection

public SkewAdvection()

Method Detail

evalBX

public double evalBX(Node n)

Specified by:

evalBX in class AbstractCDA

evalBY

public double evalBY(Node n)

Specified by:

evalBY in class AbstractCDA

evalF

public double evalF(Node u)

Description copied from class: Assembler

Evaluates the right hand side function f on the Node n

Specified by:

evalF in class Assembler

Parameters:

u - the Node where f is evaluated

Returns:

the evaluation value

getPreferredGridFileName

public java.lang.String getPreferredGridFileName()

Description copied from class: Assembler

Every Assembler has a preferred grid. If this method is not implemented in the specific assembler class, "square.grid" is default.

Overrides:

getPreferredGridFileName in class Assembler

Returns:

the file name of the preferred grid as a String object.

toString

public java.lang.String toString()

Description copied from class: Assembler

Set the name of your assembler by overwriting this method in your assembler class.

Specified by:

toString in class Assembler

Returns:

the name of the assembler

evalExactSolution

public double evalExactSolution(Node n)

Description copied from class: Assembler

For error calculations we need to know the exact solution of a problem. If we don't know that, return 0.0 for every node n.

Overrides:

evalExactSolution in class Assembler

Parameters:

n - node where the exact solution should be evaluated

getErrorCalculator

public ErrorCalculator getErrorCalculator()

Overrides:

getErrorCalculator in class Assembler
