Finite‐element method for time‐dependent euler equation

摘要

AbstractThis paper presents finite element methods to approximate inviscid incompressible flow problems.First we emphasize the conservation properties of these problems, and we show that finite element methods appear as a very natural way to find conservative schemes such as Arakawa's scheme. We give convergence theorems and an error analysis of finite element discretization schemes. We turn then to the time differencing problem. We derive stability and convergence results for a second‐order semi‐implicit scheme and for the leap‐frog s
