ShapeNumerical

public ShapeNumerical(Solution solution)

Creates an instance of the class

Parameters:

solution - Values defining the shape numerically

Method Detail

isComplex

public boolean isComplex()

Test if the function is complex

Specified by:

isComplex in class ShapeFunction

Returns:

true if complex function

getValue

public double getValue(Mesh mesh,
                       int index)

Returns the shape on a discrete mesh point position. In a future version, this should include a real interpolation, since the mesh coordinates may not coincide with the data !

Specified by:

getValue in class ShapeFunction

Parameters:

mesh - The mesh coordinates. Now Ignored.

index - The mesh index

Returns:

The value of the function at the specified mesh location

getValueC

public Complex getValueC(Mesh mesh,
                         int index)

Evaluates complex shape on a discrete mesh point position.

Specified by:

getValueC in class ShapeFunction

Parameters:

mesh - The mesh coordinates

index - The mesh index

Returns:

The value of the function at the specified mesh location

getSampling

public double getSampling(Mesh mesh,
                          int index)

Returns initial distribution of samplers

Specified by:

getSampling in class ShapeFunction

Parameters:

mesh - The mesh coordinates

index - The mesh index

Returns:

The initial distribution of samplers
