Abstract

An interface-adaptive finite-element iteration scheme is designed to solve for the free interface of an inviscid steady-state density current. The method is also applied to free-surface flows over finite obstacles, but convergent solutions are obtained only for the supercritical flows. The success and failure of the method are discussed in association with the flow properties.
