A Fictitious Domain Method with Mixed Finite Elements for Elastodynamics
We consider in this paper the wave scattering problem by an object with Neumann boundary conditions in an anisotropic elastic body. To obtain an efficient numerical method (permitting the use of regular grids) we follow a fictitious domain approach coupled with a first order velocity stress formulation for elastodynamics. We first observe that the method does not always converge when the Qdiv 1...
متن کاملA fictitious domain/finite element method for particulate flows
The paper presents a finite element method for the direct numerical simulation of 3D incompressible fluid flows with suspended rigid particles. It uses the fictitious domain approach extending the fluid domain into the domain occupied by the particles. Although the idea for the present formulation came from the fictitious domain formulation of Glowinski et al. [J. Comput. Phys. 169 (2001) 363] ...
متن کاملBalancing Domain Decomposition for Mixed Finite Elements
The rate of convergence of the Balancing Domain Decomposition method applied to the mixed finite element discretization of second-order elliptic equations is analyzed. The Balancing Domain Decomposition method, introduced recently by Mandel, is a substructuring method that involves at each iteration the solution of a local problem with Dirichlet data, a local problem with Neumann data, and a "c...
متن کاملFictitious domain finite element methods using cut elements: II. A stabilized Nitsche method
We extend the classical Nitsche type weak boundary conditions to a fictitious domain setting. An additional penalty term, acting on the jumps of the gradients over element faces in the interface zone, is added to ensure that the conditioning of the matrix is independent of how the boundary cuts the mesh. Optimal a priori error estimates in the H1 and L2 norms are proved as well as an upper boun...
متن کاملFictitious Domain Methods Using Cut Elements: Iii. a Stabilized Nitsche Method for Stokes’ Problem
We extend our results on fictitious domain methods for Poisson’s problem to the case of incompressible elasticity, or Stokes’ problem. The mesh is not fitted to the domain boundary. Instead boundary conditions are imposed using a stabilized Nitsche type approach. Control of the non-physical degrees of freedom, i.e., those outside the physical domain, is obtained thanks to a ghost penalty term f...
