Generate OptiStruct or Nastran files for different speeds for vibro-acoustic analysis.

Note: For more details about this macro, consult this additional document


  • Angpos rotor parameter
  • Case parameter
  • Number of cases (speeds)
  • Minimal angle of the scenario (in degree)
  • Maximal angle of the scenario (in degree)
  • Radius (in meter)
  • Slot opening angle (in degree)
  • Computation support
  • Name of force computation
  • Name of exported files
  • Overwrite existing force computation
  • Format (1=Nastran .bulk, 2=OS .fem, …)
  • If format =1 or 2, number of harmonics
  • Export only global DLOAD


  • Create one file of force for each case (speed)
