About the error

Issue: Occurs when there is no displacement restraint set up or if the problem setup is wrong. Applies to:
  • Static Analysis
  • Buckling Analysis
  • Modal Analysis
  • Topology Optimization
Cause:
  • The displacement restraints are not defined or are over defined.
Solution:
  • Isolate the Displacement restraints to check if they have been set up correctly and run the simulation again.
