ErrorCalculatorCompare

public ErrorCalculatorCompare(Assembler a)

Method Detail

setSolution

public void setSolution(Vector sol)

Description copied from class: ErrorCalculator

Sets a solution to this ErrorCalculator.

Overrides:

setSolution in class ErrorCalculator

Parameters:

sol - the solution to be set (adds the Dirichlet Nodes to that solution)

report

public void report()

Specified by:

report in interface Reportable

Overrides:

report in class ErrorCalculator

getMaxError

public double getMaxError()

Description copied from class: ErrorCalculator

Gets the pointwise maximal error compared to the exact solution. The points that are considered here are all the global dofs and all boundary nodes (we really would not need them, but I used the paintNodes for this, and they're in here. Remember that the getExactValue mathod has to be implemented correctly for this.

Overrides:

getMaxError in class ErrorCalculator

Returns:

getL2Error

public double getL2Error()

Description copied from class: ErrorCalculator

Returns the L2 error to the FEM solution x. Remember that the getExactValue mathod has to be implemented correctly for this.

Overrides:

getL2Error in class ErrorCalculator

Returns:

the L2 error

getH1Error

public double getH1Error()

Overrides:

getH1Error in class ErrorCalculator
