LaplaceAssemblerLReg

public LaplaceAssemblerLReg()

Method Detail

evalF

public double evalF(Node n)

Description copied from class: Assembler

Evaluates the right hand side function f on the Node n

Overrides:

evalF in class LaplaceAssembler

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 LaplaceAssembler

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 LaplaceAssembler

Parameters:

n - node where the exact gradient should be evaluated

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.

Overrides:

toString in class LaplaceAssembler

Returns:

the name of the assembler
