Abstract
A two-level nite element method is introduced and its application to the Helmholtz equation is considered.
The method retains the desirable features of the Galerkin method enriched with residual-free bubbles, while
it is not limited to discretizations using elements with simple geometry. The method can be applied to other
equations and to irregular-shaped domains
