✦ Synopsis

A new numerical technique is presented that has many advantages for obtaining solutions to a wide variety of time-dependent Arbitrary Lagrangian-Eulerian (ALE) technique [2]. A multidimensional fluid dynamics problems. The method uses a fischeme of this nature has previously been reported by nite difference mesh with vertices that may be moved with the fluid Trulio [3] for compressible flow problems. This new tech-(Lagrangian), be held fixed (Eulerian), or be moved in any other nique, however, may be applied to flows at any speed, prescribed manner, as in the Arbitrary Lagrangian-Eulerian (ALE)

since it has an implicit formulation similar to that in the technique. In addition, it employs an implicit formulation similar to Implicit Continuous-fluid Eulerian (ICE) method [4]. In that of the Implicit Continuous-fluid Eulerian (ICE) technique, making it applicable to flows at all speeds.
