The Source Stabilized Galerkin Formulation for Linear Moving Conductor Problems with Edge Elements
نویسندگان
چکیده
The phenomenon of linear motion conductor in a magnetic field is commonly found electric machineries such as, electromagnetic brakes, induction motor, flowmeter etc. design and analysis the same requires an accurate evaluation induced currents associated reaction fields. finite element method generally employed numerical technique for this purpose. However, it needs stabilization techniques to provide solution. In work, developed edge elements. stability hence accuracy brought by suitable representation source term. proposed scheme first shown analytically then demonstrated with help 2D 3D simulations. parameter-free would require graded regular mesh along direction motion.

Efficient Solvers for a Linear Stochastic Galerkin Mixed Formulation of Diffusion Problems with Random Data
Abstract. We introduce a stochastic Galerkin mixed formulation of the steady-state diffusion equation and focus on the efficient iterative solution of the saddle-point systems obtained by combining standard finite element discretisations with two distinct types of stochastic basis functions. So-called mean-based preconditioners, based on fast solvers for scalar diffusion problems, are introduce...

متن کاملStabilized Finite Elements for Elastohydrodynamic Lubrication Problems
In this work, we are mainly interested in modelling a particular lubrication regime known as Elastohydrodynamic (EHD). The pressure generated in the conjunction is high enough to induce a significant elastic deformation of the contacting bodies. Therefore a strong coupling between hydrodynamic and elastic effects is involved. A finite element full-system approach is used to model the lubricant ...
متن کاملBubble stabilized discontinuous Galerkin method for parabolic and elliptic problems
In this paper we give an analysis of a bubble stabilized discontinuous Galerkin method (BSDG) for elliptic and parabolic problems. The method consists of stabilizing the numerical scheme by enriching the discontinuous finite element space elementwise by quadratic non-conforming bubbles. This approach leads to optimal convergence in the space and time discretization parameters. Moreover the dive...
متن کاملExtended Linear Formulation for Binary Quadratic Problems
We propose and test a new linearisation technique for the Binary Quadratic Problems (BQPs). We computationally prove that the new formulation, called Extended Linear Formulation, can be effective for different classes of problems in practice. Our tests are based on two sets of classical BQPs from the literature, i.e., the Unconstrained BQP and the Maximum Cut of edge-weighted graphs. Finally we...
