Snowlapse
Monday, February 8th, 2010
Noel St. John, quasi-official photographer of TheAgitator.com, made this very cool time-lapse animation of the D.C.-area’s blizzard this past weekend.
The solution is iterative but each iteration is dependent on the CFL or explicit time step. The time step we select is based on the CFL condition but instead of just using the explicit solution we iterate until the node depths are converged or a max…

As rivers go, the Mississippi is one of the world’s biggies. It’s 3.734 km (2.320 mi) long and has a watershed of more than 3,2 million sq. km (1.245.000 sq. mi), the third-largest in the world (preceded only by the Amazon and Congo rivers), drai…
