assemblePair

public abstract double assemblePair(Grid g,
                                    Triangle t,
                                    Matrix m,
                                    java.lang.Object u1,
                                    java.lang.Object v1)

The concrete matrix-entry-assemble method returning the double value to the two DOF Objects u1 and v1. Basically it returns only the pre- calculated values from the local element matrix.

Parameters:

grid - the current grid

t - the current triangle

m - the global matrix

u1 - the first DOF object

u2 - the second DOF object

Returns:

the calculated value for the objects u1 and u2

assembleGlobal

public void assembleGlobal()

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:
