Coupling of finite element and boundary integral methods for a capsule in a Stokes flow
We introduce a new numerical method to model the fluid–structure interaction between a microcapsule 9 and an external flow. An explicit finite element method is used to model the large deformation of the capsule wall, which is treated as a bidimensional hyperelastic membrane. It is coupled with a boundary 11 integral method to solve for the internal and external Stokes flows. Our results are co...
متن کاملCoupling of finite element and boundary integral methods for electromagnetic scattering in a two-layered medium
Consider a time-harmonic electromagnetic plane wave incident on an inhomogeneity embedded in a two-layered medium. In this paper, a method of coupling of finite element and boundary integral equation methods is presented for the solutions of electromagnetic scattering in both transverse electric and magnetic polarization cases. The well-posedness of the continuous and discrete problems, as well...
متن کاملon the coupling of finite and boundary element methods for the helmholtz equation
finite and boundary element methods have been used by many authors to solve mathematicalphysics problems. however, the coupling of these two methods happens to be more efficient as it combinestheir merits. in this paper, the mathematical analysis of the coupling of finite and boundary element methodsfor the helmholtz equation is presented.
متن کاملCoupling Methods for Interior Penalty Discontinuous Galerkin Finite Element Methods and Boundary Element Methods
This paper presents three new coupling methods for interior penalty discontinuous Galerkin finite element methods and boundary element methods. The new methods allow one to use discontinuous basis functions on the interface between the subdomains represented by the finite element and boundary element methods. This feature is particularly important when discontinuous Galerkin finite element meth...
متن کاملAnalysis of Finite Element Methods and Domain Decomposition Algorithms for a Fluid-Solid Interaction Problem
This paper concerns with the nite element Galerkin approximations for a uid{ solid interaction model proposed in [10]. Both Continuous{time and discrete{time approximations are formulated and analyzed. Optimal order a priori estimates for the errors in L (H) and L(L) are derived. The main di culty for the optimal order error estimates is caused by the interface conditions which describe the int...
