This paper represents the evaluation of capacitance of different conducting bodies are calculated using finite element method (FEM). There are different numerical methods like Finite Difference method, Method of Moment and Monte Carlo methods. But the finite element method has more advantages. The surfaces are discretized using triangular subsections. Finite element method is a suitable method ...

The Finite Cell Method (FCM), which combines the fictitious domain concept with high-order p-FEM, permits the effective solution of problems with very complex geometry, since it circumvents the computationally expensive mesh generation and guarantees exponential convergence rates for smooth problems. The present contribution deals with the coupling of the FCM approach, which has been applied so...

We present efficient domain decomposition solvers for a class of non-standard finite element methods (FEM). These methods utilize PDE-harmonic trial functions in every element of a polyhedral mesh, and use boundary element techniques locally in order to assemble the finite element stiffness matrices. For these reasons, the terms BEMbased FEM or Trefftz-FEM are sometimes used in connection with ...

A numerical approach based on the extended finite element method efficiency and level set method flexibility is proposed in the present paper for the shape optimization of a switched reluctance motor pole. Using the extended finite element method as an analysis tool, an unstructured and non-conform mesh to the moving interfaces is generated only once, at the beginning of the optimization proces...

Fatigue fractures of the femoral component of cementless hip prostheses are rare occurrences at present, but may become more widespread in the future as the demand increases for porous coated cementless hip arthroplasty in young, active, and heavy patients. Whereas the fatigue fracture of high strength forged alloys is unlikely, a risk of fatigue fracture may exist for sintered porous coated st...

We present a two-scale finite element method for solving Brinkman’s and Darcy’s equations. These systems of equations model fluid flows in highly porous and porous media, respectively. The method uses a recently proposed discontinuous Galerkin FEM for Stokes’ equations by Wang and Ye and the concept of subgrid approximation developed by Arbogast for Darcy’s equations. In order to reduce the “re...

permanent magnet synchronous generators (pmsgs) are novel generators which can be used in high-performance wind farms. high efficiency and flexibility in producing electricity from variable rotation make them good candidate for wind power applications. furthermore, because these kinds of generators have no excitation winding, there is no copper loss on rotor; hence, they can operate at high pow...

PURPOSE The purpose of this study was to investigate, by finite element analysis (FEA) and fatigue analysis, the influence of different loading conditions on the stress distribution in a 3-unit implant-supported Y-TZP fixed partial denture (FPD). MATERIAL AND METHODS A three-dimensional FEM model was developed. The materials used in this study were assumed to be linearly elastic, homogeneous ...
