Abstract
The relative accuracy of several local radiation boundary conditions b ased on the second-order Bayliss-Turkel condition are evaluated. These boundary conditions permit the approximate solution of the scalar Hel mholtz equation in an infinite domain using traditional finite element and finite difference techniques, Unlike the standard Bayliss-Turkel condition, the generalizations considered here are applicable to nonci rcular solution domains. The accuracy of these conditions are investig ated for elliptical and linear/circular boundaries.
