Dynamic response analysis of an automobile is performed in parallel with distributed-memory parallel processors. Firstly, the parallel Lanczos algorithm is implemented in order to obtain partial eigensolutions. Then, parallel modal frequency response analysis is performed. This approach is effective for seamless interfacing of the parallel Lanczos method and modal frequency response analysis with industry car finite element (FE) models requiring dynamic response analysis. The performance of parallel processing is measured for large-scale industry finite element models.
