Time step control (5.0 mphase)
I'm trying to make a large-scale 2D simulation of sea ice. Seems I have a problem with time step control. I want the simulation to run for days, with dp something like 500 meters. I'm not interested in things like "sound", so there's no need to tune up the dt for such phenomena.
I have tried setting both DtFixed and DtMin to a large value, but this doesn't seem to have any effect. DualSPHysics seems to do a great number of shorter timesteps regardless. I've had some success setting CoefDtMin to something like 100 000, but this feels like a wrong way to do it.
So, basically I want a simulation of 86400 seconds to run quickly, and stay stable - but for the latter part, I've got some ideas. It's the 1st part that's problematic.
Damn. I'm using 5.0 mphase, sorry for accidentally putting this to the wrong category.
