Eulerian methods are numerical techniques used in fluid dynamics to analyze the behavior of fluids by observing how they evolve at fixed points in space over time. Unlike Lagrangian methods, which track individual fluid particles, Eulerian methods focus on the flow field and utilize partial differential equations to describe changes in properties such as velocity, pressure, and density. These methods are particularly useful for simulating complex flows like ocean currents and waves, where the spatial variation of fluid properties is crucial.
