| Abstract: |
| On the basis of research for model analysis of advanced finite element software and parallel methods for eigenvalue calculations of large scale sparse matrix, a new parallel model analysis system was provided. By means of second development to the CAE software, the serial method for eigenvalue was replaced by parallel computing. By research for Implicit Restarted Lanczos method, parallel programming based on MPI was compiled, and its speed-up and extension were tested by examples, the same time seamless integration with serial sections was implemented, which made the interface friendly and convenient. The velocity and dimensions of model analysis can be improved greatly. The parallel system took CAE software MSC/NASTRAN as development flat, and its feasibility and efficiency were tested on the supercomputer "Shen Wei I". |
