Generalized Finite Element Methods for the Helmholtz equation in
2D with minimal pollution
Dr. Stefan Sauter, University of Maryland, College Park

Using the generalized finite element method (GFEM) to solve the Helmholtz
equation in two dimensions, the error of the corresponding solution differs
from the error of the best approximation substantially and this effect
increases with higher wave numbers. This non-robust behaviour of the finite
element solution is called the pollution effect.
In our talk we will show how to design a GFEM for the Helmholtz equation such
that pollution effect is minimal.
