Method Detail

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 Assembler

createDof

public void createDof(Grid grid,
                      java.util.Set dof)

Description copied from class: Assembler

All global Objects, that represent a degreeOfFreedom are added to dof.

Overrides:

createDof in class LagrangeLinearAssembler

Parameters:

grid - the current grid

dof - the Set where the DOFs have to be put in

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 MinimalSurfaceAssembler

Parameters:

n - node where the exact solution should be evaluated

assembleElement

public void assembleElement(Triangle t)

Description copied from class: Assembler

The elementwise assemble method. It locally gets the element-matrices and sorts them into the global Matrixm. Before that, Dirichlet boundary values are handled.

Parameters:

t - the current triangle

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.

Specified by:

toString in class Assembler

Returns:

the name of the assembler
