摘要:Abstract(#br)The localized method of fundamental solutions (LMFS) is an efficient meshless collocation method that combines the concept of localization and the method of fundamental solutions (MFS). The resultant system of linear algebraic equations in the LMFS is sparse and band...

摘要:Abstract(#br)A hybrid numerical method is developed for three-dimensional (3D) heat conduction in functionally graded materials (FGMs) by integrating the advantages of the generalized finite difference method (GFDM) and Krylov deferred correction (KDC) technique. The temporal dir...

摘要:Abstract(#br)The main difficulty of the singular boundary method (SBM) is the calculation of the origin intensity factors introduced to remove the singularity of fundamental solution. This work presents an extension of the previous SBM formation. The new contribution of the prese...

摘要:Abstract(#br)This paper firstly employs the fast multipole method (FMM) to accelerate the singular boundary method (SBM) solution of the Stokes equation. We present a fast multipole singular boundary method (FMSBM) based on the combination of the SBM and the FMM. The proposed FMS...

摘要:Abstract(#br)In this paper, we present a new fast meshless method, called as wideband fast multipole singular boundary method (FMSBM), for three-dimensional acoustic problems. The wideband FMSBM applies a partial wave expansion formulation in low frequency regime and a plane wave...

摘要:Abstract(#br)The generalized finite difference method (GFDM) is a relatively new domain-type meshless method for the numerical solution of certain boundary value problems. The method involves a coupling between the Taylor series expansions and weighted moving least-squares method...

摘要:Abstract(#br)The accuracy of the method of fundamental solutions (MFS) is strongly dependent on the distribution of source points. A proper choice of source points is still an important issue in the MFS. In this paper we derive a new merit function, namely the energy gap function...

摘要:Abstract(#br)This study documents the first attempt to apply a nonsingular indirect boundary element method (BEM) for the solution of three-dimensional (3D) inverse heat conduction problems. The present BEM formulation avoids the calculation of hyper-singular integrals. Furthermo...

摘要:The presentation is mainly devoted to the research on the regularized boundary integral equations (BIEs) with indirect unknowns for torsion problem of the anisotropic uniform bar. Based on a new view and idea, a novel regularization technique is pursued, in which the nonsingular ...
