Hybrid Multigrid/Schwarz Algorithms for the Spectral Element Method
We study the performance of the multigrid method applied to spectral element (SE) discretizations of the Poisson and Helmholtz equations. Smoothers based on finite element (FE) discretizations, overlapping Schwarz methods, and point-Jacobi are considered in conjunction with conjugate gradient and GMRES acceleration techniques. It is found that Schwarz methods based on restrictions of the origin...

متن کاملCircuit Models for the Hybrid Element Method
In this paper, we describe a new hybrid method which combines the boundary element method (BEM) and the nite element method (FEM) to calculate the circuit models for layout dependent capacitances in VLSI circuits. The hybrid method which we present does more than solving a particular eld problem, it produces a good physical circuit model for the interface between the regions where the BEM and t...

متن کاملParallel Algorithms for the Spectral Transform Method
The spectral transform method is a standard numerical technique for solving partial diierential equations on a sphere and is widely used in atmospheric circulation models. Recent research has identiied several promising algorithms for implementing this method on massively parallel computers; however, no detailed comparison of the diierent algorithms has previously been attempted. In this paper,...
