- HO model; what distinguishes it from a LO model, why is it useful.
- Available HO schemes (e.g. Full Stokes, Blatter-Pattyn, Bueler & Pollard Hybrids)
- Architecture (transport, and non-linear iteration on diffusivity) of Glimmer an how it differs from a HO model architecture
- Introduce HO CISM (Blatter-Pattyn 1st-order scheme)
- Discretization and solution (elliptic solve, operator splitting approach, etc)
- Boundary conditions + masking, one sided differences, basal BC (no-slip, viscous, and plastic behavior all through Beta^2 implementation)
- Run verification suites; ISMIP-HOM, Ross IS
- Apply HO velocity fields to 1st-order upwind transport (dH/dt) scheme (see Adding a module to Glimmer I)
