Mesh Moving Methods in Flow Computations with the Space–Time and Arbitrary Lagrangian–Eulerian Methods

A good mesh moving method is an important part of ?ow computations with moving-mesh methods like the space–time (ST) and Arbitrary Lagrangian–Eulerian (ALE) methods. With a method, we can decrease remeshing frequency even when ?uid–solid ?uid–?uid interfaces undergo large displacements, element distortion in parts domain where care about solution accuracy more, maintain quality boundary layer meshes near as moves to follow those interfaces. Since 1990, quite few have been developed for use ST computational methods, from Jacobian-based sti?ening based on fiber-reinforced hyperelasticity linear-elasticity no cycle-to-cycle accumulated distortion. These used computation many complex problems categories ?uid–particle interaction, ?uid–structure more generally, boundaries The were both ALE We provide overview these present examples performed.This Open Access article distributed under terms Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, reproduction any medium provided original work properly cited.
