Parallelization of Mortar Spectral Element Method

چکیده
Our work concerns the approximation of the 2D Stokes equations solution based on a variational formulation with primitive variables: velocity and pressure. We choose to use the mortar spectral element method which is a domain decomposition technique. Since, this method has a high spatial and temporal complexity, we opted to parallel processing. We present, in this paper, two versions of sequential algorithms of the resolution of 2D Stokes equations on one domain and then on two sub-domains using mortar spectral element method. Then, we present a parallelization of these algorithms based on exploiting data parallelism and using MPI directives and language C. The performance evaluation achieved through different experiments done on IBM SP2 parallel machine, shows a wide difference in execution time between the two versions.

Coupling non-conforming discretizations of PDEs by spectral approximation of the Lagrange multiplier space
This work focuses on the development of a non-conforming domain decomposition method for the approximation of PDEs based on weakly imposed transmission conditions: the continuity of the global solution is enforced by a discrete number of Lagrange multipliers defined over the interfaces of adjacent subdomains. The method falls into the class of primal hybrid methods, which also include the well-...
متن کاملMortar spectral element discretization of the Stokes problem in axisymmetric domains
The Stokes problem in a tridimensional axisymmetric domain results into a countable family of two-dimensional problems when using the Fourier coefficients with respect to the angular variable. Relying on this dimension reduction, we propose and study a mortar spectral element discretization of the problem. Numerical experiments confirm the efficiency of this method.

We analyze the consistency, stability, and convergence of an hp discontinuous Galerkin spectral element method. The analysis is carried out simultaneously for acoustic, elastic, coupled elastic–acoustic, and electromagnetic wave propagation. Our analytical results are developed for both conforming and non-conforming approximations on hexahedral meshes using either exact integration with Legendr...
متن کاملA Mortar Finite Element Method for Plate Problems
In the paper we discuss two versions of mortar finite element methods applied to clamped plate problems. The problems are approximated by the nonconforming Morley and Adini element methods in each subregion into which the original region of the discussed problems have been partitioned. On the interfaces between subdomains and at crosspoints of subregions some continuity conditions are imposed. ...
