Method Detail

setIterationState

public void setIterationState(int current,
                              int bound)

isFinalRun

public boolean isFinalRun()

Overrides:

isFinalRun in class mathcomp.assemble.stokes.StokesAssembler

setOldSolution

public void setOldSolution(Vector x,
                           Vector yy)

getOldSolution

public Vector getOldSolution()

assembleGlobal

public void assembleGlobal()

Description copied from class: Assembler

The main assemble method generally called from outside. It once calculates the boundary, the global DOFs and the Dirichlet values. Then Matrix m and right side Vector y are created. Finally an iteration over all elements calls assemble(Grid g, Triangle t, Matrix m) for each element.

Overrides:

assembleGlobal in class mathcomp.assemble.stokes.StokesAssembler

calcDirichletBoundary

public java.util.Map calcDirichletBoundary(java.util.Map boundaryNodes)

Pre-calculation of the values at the Dirichlet boundary stored in a HashMap that maps to every Dirichlet boundary point its corresponding value by considering the boundary identifier info for this boundary segment. This method was overridden in the StokesAssembler class, to be possible to use the objects StokesNode instead of Node.

Overrides:

calcDirichletBoundary in class mathcomp.assemble.stokes.StokesAssembler

addToM

public void addToM(mathcomp.assemble.stokes.StokesNode u,
                   mathcomp.assemble.stokes.StokesNode v,
                   double d)

Description copied from class: mathcomp.assemble.stokes.StokesAssembler

This method was overridden since we don't have Newmann boundary conditions in the Stokes problem

Overrides:

addToM in class mathcomp.assemble.stokes.StokesAssembler

addToY

public void addToY(mathcomp.assemble.stokes.StokesNode n,
                   double value)

addDirichletNodes

public Vector addDirichletNodes(Vector sol)

Description copied from class: Assembler

Completes the solution vector by adding the values at the dirichlet nodes

Overrides:

addDirichletNodes in class Assembler

Parameters:

sol - the calculated solution vector

Returns:

the completed solution vector

calcUnitNormals

public java.util.Map calcUnitNormals()

setParameterBox

public void setParameterBox(ParameterBox parameterBox)

Overrides:

setParameterBox in class mathcomp.assemble.stokes.StokesAssembler

getParameterBox

public ParameterBox getParameterBox()

getType

public int getType()

Overrides:

getType in class mathcomp.assemble.stokes.StokesAssembler

setFP_parameters

public void setFP_parameters(double alpha,
                             double beta)

getBoundaryNodes

public java.util.Map getBoundaryNodes()
