Overview

Now, let's see if COMSOL can be used to solve problems of glaciological relevance. We'll look at shallow ice approximation flow, and shallow shelf approximation flows.

Shallow Ice Approximation

Begin with the often used shallow ice form for ice thickness evolution

\frac{\partial H}{\partial t} = - \nabla D \nabla H + M

where

D = \frac{2A(\rho g)^n}{n+2} H^{n+2} \left[\nabla H \cdot \nabla H \right]^{(n-1)/2}
