Residual-free bubbles for the Helmholtz equation |

| Authors: | Leopoldo P. Franca Charbel Farhat Antonini P. Macedo Michel Lesoinne |
| Abstract: | The Galerkin method enriched with residual-free bubbles is considered for approximating the solution of the Helmholtz equation. Two-dimensional tests demonstrate the improvement over the standard Galerkin method and the Galerkin-least-squares method using piecewise bilinear interpolations. © 1997 John Wiley & Sons, Ltd. |
