Method Detail

approxLHS

public double approxLHS(Triangle t,
                        Node u,
                        Node v)

Overrides:

approxLHS in class AbstractCDA_cV

evalWeightedBasisFunc

public double evalWeightedBasisFunc(Triangle t,
                                    Node n,
                                    int local)

getAverageFlux

public double[] getAverageFlux(Triangle t,
                               int local)

evalApproxSolution

public double evalApproxSolution(Node n,
                                 Triangle t,
                                 Vector x)

Description copied from class: Assembler

Evaluates the FEM solution in a Node. To do that we do need the triangle. We need this method for an easy l2 and l\infty error calculation.

Overrides:

evalApproxSolution in class LagrangeLinearAssembler

Parameters:

n - Node where the solution has to be evaluated

t - the triangle that contains the Node n

x - the solution vector

Returns:

the value of the solution in n

evalApproxGradient

public double[] evalApproxGradient(Node n,
                                   Triangle t,
                                   Vector x)

TODO adjust linear to weighted gradients

Overrides:

evalApproxGradient in class LagrangeLinearAssembler

Parameters:

n - node where the approximated 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.

Overrides:

toString in class ConvDiffHomogen

Returns:

the name of the assembler
