Artificial damping techniques for scalar waves in the frequency domain
An artificial damping algorithm for solving the Helmholtz equation is considered when the imaginary part of the wave number is small. The artificial damping algorithm can be viewed as a rational iteration. Each damped problem is solved incompletely by a nonoverlapping domain decomposition method. Numerical tests on nCUBE2 are presented.
