Description
This paper investigates a new method for computing waveforms generated by independent sources. A global spacetime evolution algorithms based on the Cauchy initial-value approach is used for the bounded interior area and the same algorithm based on the characteristic hypersurfaces is used for the exterior region. Both methods are equated at the common interface
