The discretization of the boundary in boundary element method generates integrals over elements that can be evaluated using numerical quadrature that approximate the integrands or semi-analytical schemes that approximate the integration path. In semi-analytical integration schemes, the integration p

✦ Synopsis
In this letter, a hybrid algorithm combining the direct method with the iterati¨e method is designed for sol¨ing the FE᎐BI matrix equation, which not only can take full ad¨antage of the multile¨el ( ) fast multipole algorithm MLFMA , but also can significantly speed up the rate of con¨ergence. Numerical experiments demonstrate that the proposed hybrid algorithm has a significant impro¨ement in efficiency o¨er the con¨entional direct algorithm.

In this article, we represent a new numerical method for solving the nonstationary Navier-Stokes equations in an unbounded domain. The technique consists of coupling the boundary integral and the finite element method. The variational formulation and the well-posedness of the coupling method are obt
We propose and analyze efficient preconditioners for solving systems of equations arising from the p-version for the finite element/boundary element coupling. The first preconditioner amounts to a block Jacobi method, whereas the second one is partly given by diagonal scaling. We use the generalized
A coupled finite element and boundary element method is developed to predict the magnetic vector and scalar potential distributions in the droplets levitated in an alternating magnetic or electrostatic field. The computational algorithm entails the application of boundary elements in the region of f
