Journal ArticleDOI
A Level Set Method in Shape and Topology Optimization for Variational Inequalities
TL;DR: Numerical results confirm that the level set method for shape optimization of the energy functional for the Signorini problem is efficient and gives better results compared with the classical shape optimization techniques.
Journal ArticleDOI
An Initial and Boundary Value Problem Modeling of Fish-like Swimming
TL;DR: In this paper, an initial and boundary value problem that models the self-propelled motion of solids in a bidimensional viscous incompressible fluid is considered, consisting of appropriate deformations of the solids, is a simplified model of the propulsion mechanism of fish-like swimmers.
Journal ArticleDOI
Controllability and Time Optimal Control for Low Reynolds Numbers Swimmers
TL;DR: In this article, the controllability problem of self-propelling at low Reynolds number was addressed by using tools coming from control theory, and the necessary optimality conditions were derived by using the Pontryagin maximum principle.
Journal ArticleDOI
Level set method with topological derivatives in shape optimization
TL;DR: Examples show that the level set method combined with the asymptotic analysis is robust for the shape optimization problems, and it allows us to identify the better solution compared to the purelevel set method exclusively based on the boundary variation technique.
Journal ArticleDOI
Convergence of the Lagrange--Galerkin Method for the Equations Modelling the Motion of a Fluid-Rigid System
TL;DR: A Lagrange--Galerkin scheme to approximate a two-dimensional fluid-rigid body problem based on the use of characteristics and on finite elements with a fixed mesh is considered and the main result asserts the convergence of this scheme.
