Modeling ice streams with Finite Element Methods
An idealized ice stream seen from below. The
color scale shows speed. The ice sheet
surrounding the ice stream is kept frozen. The
grid is also shown. Note the result of the
adaptive grid refinement that allows better
resolution in areas of higher gradients. This is
crucial for a successful model.
