From linear to nonlinear with MSC Nastran



You will learn how to get started efficiently with nonlinear calculations. There are many reasons, from the linear move to non-linear calculation: large deformations, non-linear material properties, more non-linear Contact or thermo-mechanical coupling. If you are already working with linear solutions, the formal one is transition easy. Nevertheless, you have to take into account the additional effects of the non-linear calculation, which are unfamiliar. Error messages can result: additional degrees of freedom due to other AUTOSPC defaults, nonlinear RBEs or Iteration parameters affecting accuracy and performance. 


  • Reasons for nonlinear calculation: Large deformations and strains, non-linear loads (follower forces) and material properties, Nonlinear Contact, Thermomechanical Coupling, screw preload 
  • What is different in the nonlinear calculation? 
    • Typical messages in the f06 file when using SOL101 changes in SOL400
    • Additional degrees of freedom
    • AUTOSPC settings
    • Linear and non-linear elements
    • RBEs - from linear to Lagrangian
    • Differential stiffness in beam and shell offsets
    • Analysis chaining - subcases and steps
  • Nonlinear iteration and convergence
  • Nonlinear and elastoplastic materials
  • Composite failure
  • Glued Contact, linear and non-linear contacts
