Eigenvalue analysis of structural models is a common analysis task. Often the lowest natural frequencies are directly related to some performance index of the structure. In addition, eigenvalue information is used to create a modal reduction of the structural model to reduce the cost of frequency response and/or transient dynamic analysis. Therefore, an improvement in the performance of the eigensolution process will have a direct effect on many analysis tasks. Vanderplaats Research & Development (VR&D) introduces a new eigenvalue solver implementation that dramatically reduces both the CPU and elapsed times for all ranges of problem sizes compared to the current state-of-the-art Lanczos algorithm. This new solver, named SMS, will be available in the upcoming GENESIS Structural Analysis and Optimization Software Version 7.0 release, as well as in a new stand-alone product, Vrand/SMS.
