The motion of an incompressible, inviscid fluid in a region surrounded by a massless, elastic membrane can be approximated by transmitting the effect of the boundary forces to the fluid through vortex dipoles, We present a Lagrangian numerical method for approximating this motion based on the impulse (a.k.a. magnetization) variables introduced by Buttke. In particular, we explain the correspondence between impulse variables and vortex dipoles with a prescribed dipole moment. Numerical examples that illustrate the application of impulse variables in this context are given. 26 refs., 10 figs., 2 tabs.
