In computation of fluid-structure interactions, we use mesh update methods consisting of mesh-moving and remeshing-as-needed. When the geometries lire complex and the structural displacements are large, it becomes even more important that the mesh moving techniques lire designed with the objective to reduce the frequency of remeshing. To that end, we present here mesh moving techniques where the motion of the nodes is governed by the equations of elasticity, with selective treatment of mesh…

A simple mesh deformation technique for fluid–structure interaction based on a submesh approach

This paper describes an improvement in techniques currently used for mesh deformations in fluid–structure calculations in which large body motions are encountered. The proposed approach moving

Finite element modeling of fluid – structure interactions with space – time and advanced mesh update techniques

TLDR

Moving mesh for complex geometries

TLDR
This research report presents an overview on moving mesh methods used in the literature, several mesh deformation methods are proposed, local remeshing operations are explained and finally different approaches that uses PDE are detailed.

Mesh Moving Scheme Based on Solving the Laplace Equation with Jacobian Stiffening Technique

Mesh moving scheme is an important issue in many fluid-structure interaction problems. In this paper a new mesh motion technique is presented for the effective treatment of moving mesh. The entire

A linear-elasticity-based mesh moving method with no cycle-to-cycle accumulated distortion

TLDR
The back-cycle-based mesh moving (BCBMM) method, introduced recently with two versions, can remedy the problem of cycle-to-cycle accumulated mesh distortion, and this article presents mesh moving test computations with the BCBMM for the first time.

Moving boundary simulations with dynamic mesh smoothing

We develop a dynamic mesh adjustment scheme for moving boundary problems such as those encountered in fluid–structure interaction. The scheme is implemented in an arbitrary Lagrangian–Eulerian (ALE)

A mesh moving technique with minimum-height-based stiffening for fluid-structure interaction analysis

The practical use of the fluid-structure interactions (FSI) analysis system requires the robustness for the parametric design of artifacts. In the FSI analysis employing interface tracking methods,

A minimal element distortion strategy for computational mesh dynamics

TLDR
The mesh motion strategy is defined as an optimization problem where the material constitutive law is defined in terms of the minimization of certain energy functional that takes into account the degree of element distortion.
