SquareLaplaceAssembler

public SquareLaplaceAssembler()

Method Detail

evalF

public double evalF(Node n)

Description copied from class: Assembler

Evaluates the right hand side function f on the Node n

Specified by:

evalF in class Assembler

Parameters:

n - the Node where f is evaluated

Returns:

the evaluation value

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

evalExactGradient

public double[] evalExactGradient(Node n)

Description copied from class: Assembler

For H1 error calculations we need to know the exact gradient of a problem. If we don't know that, return [0.0,0.0] for every node n. TODO this should become abstract.

Overrides:

evalExactGradient in class Assembler

Parameters:

n - node where the exact gradient should be evaluated

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
