WebThis paper describes an Arbitrary Lagrangian- Eulerian (ALE) finite element method for the simulation of fluid domains with moving structures. The fluid is viscous, incompressible and unsteady and the fluid motion is solved by a fractional step discretization of the Navier-Stokes equations. The emphasis is on convection dominated flows, and a three-step … Web1 gen 1995 · arbitrary Lagrangian-Eulerian techniques, finite element, numerical techniques, subduction models, tectonics, viscoplastic flows Issue Section: Articles References Babuska I. , 1973 .
