In RFEM, you can use these three powerful eigenvalue solvers:

  • Root of Characteristic Polynomial
  • Method by Lanczos
  • Subspace Iteration

RSTAB, on the other hand, provides you with these two eigenvalue solvers:

  • Subspace Iteration
  • Shifted inverse power method

The selection of the eigenvalue solver depends primarily on your model size.
