Convergence of a Lagrange-Galerkin method for a fluid-rigid body system in ALE formulation

Abstract: Abstract. We propose a numerical scheme to compute the motion of a two-dimensional rigid body in a viscous fluid. Our method combines the method of characteristics with a finite element approximation to solve an ALE formulation of the problem. We derive error estimates implying the convergence of the scheme.Mathematics Subject Classification. 35Q30, 65M12, 76D05, 76M10.

“…The development of efficient numerical methods for the simulation of fluid-structure interaction problems is a great challenge. On one hand some methods are based on meshes which fit to the geometry of the computational domain, like in [11,18,19] for instance. In that case re-meshing is necessary when the geometry is led to evolve, which can be greedy in resources, especially for complex problems.…”
