ON THE CHOICE OF TIME WINDOW LENGTH FOR WAVEFORM ITERATIONS FOR COUPLED PROBLEMS

Abstract
e consider waveform iterations for dynamic coupled problems with respect to the
role of time window length. We review existing theoretical results about the error of waveform
iterations and the role of the time window length. Furthermore, we present numerical results
for waveform iterations with both time adaptive sub solvers and with fixed time steps. This
way, we are able to give a recommendation on the choice of the time window. The use of time
windows can lead to an increase in efficiency. For fixed time grids, we can reliably achieve a
small performance increase. For time adaptive solvers, more research is needed.
