Hi Bruno,

I tried to use GlobalStiffnessTimeStepper, but it keeps setting dt to
defaultDt at start. Since defaultDt is maximum at the same time (why?),
then I can't assign a sensible value to it: I want GSTS to set dt higher
than p-wave, without constraining it by a conservative estimate of dt
from p-wave.

I think the default should be to not touch dt if nothing is computed.
Would it make better sense?

Cheers, Vaclav
