Hi Evan,
I am having the very same problem you posted to the CIG-SEISMO mailing
list in October. Did you finally find a solution to this?
I am testing different models that I generate based on the software that
I want to benchmark (AXISEM) and it seems that some models have less
problems then others, but I don't see any systematics. As soon as I want
to go to higher frequencies then 30mHz it seems to be more or less
random whether it works or not.
The other thing I am worrying about in this context is the "raylquo"
output in the output of minos brans: according to the manual it should
be on the order of "eps", but there are always modes where it goes up to
the order of 1, no matter what eps I choose as input.
Any hint would be apreciated,
Thanks,
Martin van Driel
