A multigrid approach for the solution of the 2D semiconductor equations:
Abstract: "In this paper a multigrid method is presented for the solution of the steady semiconductor equations. The discretisation is made on an adaptive grid, by means of a Mixed Finite Element Method on rectangles, with the trapezoidal quadrature rule. In 1D the resulting scheme reduces to t...

| Zusammenfassung: | Abstract: "In this paper a multigrid method is presented for the solution of the steady semiconductor equations. The discretisation is made on an adaptive grid, by means of a Mixed Finite Element Method on rectangles, with the trapezoidal quadrature rule. In 1D the resulting scheme reduces to the well known Scharfetter-Gummel discretisation. The grid transfer operators are selected in accordance with the discretisation. The multigrid solution method is based on a collective, symmetric 5-point Vanka relaxation, and -in order to admit very coarse grids- a local damping of the coarse grid collection is applied It is shown that the convergence rate is independent of the grid size. Since nested iteration is combined with the multigrid iteration, the resulting solution method has optimal efficiency. |
