We consider domain decomposition preconditioners for the linear algebraic equations which result from finite element discretization of problems involving the bilinear form α (·, ·) + ( curl ·, curl ·) defined on a polyhedral domain ष. Here (·, ·) denotes the inner product in ( L 2 (ष))...
Edge-oriented stabilization methods in the framework of discontinuous Galerkin approaches have been recently proposed by Brenner Korn's inequalities for piecewise H 1 vector fields, University of South Carolina, 2002 and particularly by Hansbo and Larson A simple nonconforming bilinear element...
This paper provides a short Matlab implementation with documentation of the P 1 finite element method for the numerical solution of viscoplastic and elastoplastic evolution problems in 2D and 3D for von-Mises yield functions and Prandtl-Reuß flow rules. The material behaviour includes perfect...
The finite element method approximates the spectrum of an operator S by computing the spectra of a sequence of operators S N defined in terms of the finite element spaces. For the case that S is compact, convergence of the approximate spectra follows from the convergence of S N to S in the...
