2d Ice Shelf without Grounding Line
Posted: 18 Jul 2014, 17:19
Hi Elmers,
I have troubles with an ice-shelf model (prognostic, 2D, flowline, no grounding line). I start from a block, prescribe the flux at the back and the pressure at the bottom & front. I do get nice steady state profiles, however, the final shape unfortunately depends strongly on the time-stepping size and the spatial gridding (I attached a snapshot for dt=0.03,0.1,0.3 years). The system becomes more instable when increasing the horizontal resolution; using the Normal-Tangential Velocity at the bottom does not work.
Does anybody have experience with simple ice-shelf models that do not include a grounding line? I would be grateful if somebody could have a look at the attached zip file ("make compile all2d" should make it run).
Greetings, Reinhard
