Where to start on a transient grounding line model
Posted: 02 Dec 2020, 00:03
So I just finished the Elmer Beginners course and have an okay idea of how the components work, but I am a bit lost in starting to create my own model runs.
I want to eventually have a 2D marine-terminating ice stream and I want to model the movement of the grounding line subject to various forces (for example sea level rise).
I understand the basic pieces of what I need to do,
create an extruded mesh with an area of higher resolution near the grounding line
for my bodies, I believe I need 3, the ice itself, an upper free surface and the ocean water.
For boundary conditions, I believe there are 2, the bedrock, the calving front.
for body forces, there is the pressure of the ocean, and of course gravity.
I'm not too worried about temperature right now so for solvers I believe I need a flotation check, as well as a full stokes solver and an upper free surface solver, as well as potentially a few solvers to export data or to read in my initial conditions.
If anyone has any suggestions about how this sounds or knows of any currently existing models which solve this, I'd be grateful for any help!
