Re: 2d Ice Shelf without Grounding Line

To finish this thread: As suspected by Olivier the Case more or less works. I did some more testing with with the time stepping and the horizontal resolution and it turns out that for a given grid the solution is consistent if the time steps are small enough (e.g. 0.05 and below). I still have probl...

Re: 2d Ice Shelf without Grounding Line

Hi Olivier, thanks for the quick reply. To prescribe the flux, I scale the x-velocity in the incoming BC with the ice thickness of the current time step. I double checked (depth+height)*velocity_X in Paraview and it stays constant at the inflow boundary (x=0). However, for the case of zero accumulat...

2d Ice Shelf without Grounding Line

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-...

Restarting Advection Reaction Solver for Age Equation

Hi Elmers, I have a small problem with solving the Age Equation: I implemented the Advection-Reaction Solver as in the Example described here: http://elmerice.elmerfem.org/wiki/doku.php?id=solvers:dating and it works fine. Using the same solver in combination with a Restart File from a previous run ...
