RF-/DYNAM Pro - Natural Vibrations | Calculation

Product Feature

The RF-DYNAM Pro - Natural Vibrations module for RFEM provides four powerful eigenvalue solvers:
  • Root of the characteristic polynomial
  • Lanczos method
  • Subspace iteration
  • ICG iteration method (Incomplete Conjugate Gradient)

The DYNAM Pro - Natural Vibrations module for RSTAB provides two eigenvalue solvers:
  • Subspace iteration
  • Shifted inverse iteration

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