Is there documentation that compares FFT and Multigrid "side by side"

Thanks

Not really. But we're more and more getting a feeling that MultiGrid works better. Some examples have been seen where FFT doesn't give correct results. This is the subject of current investigations, so that we can make a proper decision for the future.
