We describe, for simulation of flows with moving interfaces, a computational method based on the edge‐tracked interface locator technique (ETILT). The method described has been designed by bearing in mind the ease in managing a node‐based interface representation and the interface sharpness and volume conservation features of the Moving Lagrangian Interface Technique. We evaluate the performance of the method with a number of test problems: filling of a step cavity, gravity‐driven flow of an aluminium alloy in an obstructed channel, collapse of a liquid column, and the bore problem.
