SMS Eigen Solver

High Performance Computing Software

SMS is an external matrix solver software used to extract eigenvalues and eigenvectors extremely fast compared with a traditional solver like Lanczos. VR&D/SMS is a plug-in for MSC.NASTRAN (from MSC.Software) that uses SMS to solve the eigenproblem for solution sequences 103, 111, 112 and 200.


  • Small to midsize problems run from 2 to 5 times faster than the conventional Lanczos method.
  • Large scale problems run from 5 to 10 times faster.
