Summary form only given. We present our progress on an accelerated algorithm for resolving wave reflections in the parametric, multi-frequency, TWT simulation code CHRISTINE. On the average, it achieves a speedup factor of at least 10 compared with the previously used Newton-type iterative algorithm.Wave reflections in CHRISTINE are modeled by the coupled wave equations for the forward and backward...
We present our progress on a framework for efficient computer simulation of complex time-dependent waveforms (i.e. wideband, with large number of Fourier components) on massively parallel computer platforms. It is based on the parametric multi-frequency large-signal code CHRISTINE and relies on an adaptive algorithm for signal splitting and splicing in the time domain. Included in the model are memory...
