Subspace and Lanczos sparse eigen-solvers for finite element structural and electromagnetic applications

Recent developments in vectorized sparse technologies are incorporated into the Subspace and Lanczos iteration algorithms for computational enhancemen ts. Numerical evaluations of the proposed sparse strategies for Subspace an d Lanczos iteration algorithms are conducted by solving the generalized eig en-value problem associated with the Exxon-off-shore structure, HSCT aircra ft and a two-dimensional reverberation chamber for electromagnetic applicat ions. Both real and complex numbers eigen-problems can be treated. (C) 2000 Elsevier Science Ltd. All rights reserved.
