I was trying to use a Bolt Preload and Enforced Displacement Constraint in one model using SOL 101 and am getting the error:
USER FATAL MESSAGE 22102 (BOLTFOR) SPECIFIED DISPLACEMENTS (SPCD) NOT PERMITTED IN A PRELOADED BOLT ANALYSIS
Is there a way to use the bolt preload in a model with specified displacements?
Just make sure that the same bolt preload is selected into the Load container in every subcase in the solution.
non-zero displacements can be defined in two ways in NX NASTRAN:
- as Enforced displacements (SPCD) and
- as User defined constraints (SPC) of third type (free, fixed, displacement).
May be it works if you choose the other.
I can also remember that if you define a SPCD bulk data entry card in NASTRAN you have to define a SPC bulk data entry for the same gid point DOF. But I'm not sure if it was in NX NASTRAN or MSC NASTRAN and at which version number.
Try it and tell me your results here.
Best wishes, Michael
