Adding a module to Glimmer I
Construct and add a new module to Glimmer
- For this exercise, we will create and add a 1st-order, upwind advection scheme to the model
- The new module will be used with velocities from the HO model to evolve a simple ice shelf domain (image below).
- Evolution using the 1st-order advection scheme will be compared with that from a higher-order advection scheme.
- For step-by-step notes on adding this module, go to adding dH/dt module.
Initial thickness, across-flow, and along-flow velocity fields for confined ice shelf (500 m thick, uniform T=253 K). Boundary conditions are 0-flux at top, left, right, and shelf BCs at bottom.
Thickness and velocity fields after 100 yrs of evolution with no accumulation. Evolution was calculated using the 1st-order advection scheme.
Steady state thickness and velocity fields with uniform accumulation of 0.5 m/a. Evolution was calculated using the 1st-order advection scheme.
