ABSTRACT

Over the past several years I have been developing a new Lagrangian ocean model. The model is based on the slippery sacks (SS) numerical method, under which a fluid is represented as a pile of conforming sacks. During this talk I will introduce the SS method and present tests in which SS simulations are compared to analytic solutions and simulations carried out with other models. The simulated circulations will range in complexity from idealized waves to the three dimensional flow in a large lake. I will discuss the numerical accuracy, the computational efficiency (for both single- and multi-processor simulations), and the advantages and disadvantages of the SS model.
