A combined nodal continuous-discontinuous finite element formulation for the Maxwell problem
Continuous Galerkin formulations are appealing for their low computational cost, whereas discontinuous Galerkin formulation facilitate adaptative mesh refinement and are more accurate in regions with jumps of physical parameters. Since many electromagnetic problems involve materials with different physical properties, this last point is quite important. For this reason, in this article we have ...
متن کاملA New Finite Element Formulation for Electromechanics
ABSTRACT A new finite element formulation for the solution of electromechanical boundary value problems is presented. As opposed to the standard formulation that utilizes a scalar electric potential as nodal variables, this new formulation implements a vector potential from which components of electric displacement are derived. For linear piezoelectric materials with positive definite material ...
متن کاملDistributed Algebraic Multigrid for Finite Element Computations
The Finite Element Method has been successfully applied to a variety of problems in engineering, medicine, biology, and physics. However, this method can be computationally intensive, particularly for problems in which an unstructured mesh of elements is generated. In such situations, the Algebraic Multigrid (AMG) can prove to be a robust method for solving the discretized linear systems that e...
متن کاملAdaptive Finite Element Methods in Flow Computations
This article surveys recent developments of theory-based methods for mesh adaptivity and error control in the numerical solution of flow problems. The emphasis is on viscous incompressible flows governed by the Navier-Stokes equations. But also inviscid transsonic flows and viscous lowMach number flows including chemical reactions are considered. The Galerkin finite element method provides the ...
متن کاملJava Performance in Finite Element Computations
1 The performance of the developed Java finite element code is compared to that of the C finite element code on the solution of three-dimensional elasticity problems using Intel Pentium 4 computer. Untuned Java code is approximately two times slower then analogous C code. It is shown that code tuning with the use of blocking technique can provide Java/C performance ratio 90% for the LDU solutio...
