Error: "The model is insufficiently constrained for the analysis. Please review the element connections, properties, and constraints in highlighted entities" is prompted when running static analysis in Creo Simulate

Modified: 30-Mar-2018   


Applies To

  • Pro/MECHANICA and Creo Elements/Pro Mechanica Wildfire 4.0 to Wildfire 5.0
  • Creo Simulate 1.0 to 7.0

Description

  • Error: "The model is insufficiently constrained for the analysis. Please review the element connections, properties, and constraints in highlighted entities" is prompted when running static analysis
  • The analysis will terminate with fatal error.
  • Error message from Diagnostics dialog box and the summary file <analysis_name>.rpt:
    • The design study terminated abnormally.
    • The model is insufficiently constrained for the analysis. Please review the element connections, properties, and constraints. If this is a modal analysis, then you may be able to obtain a solution by requesting additional modes.
    • You may be able to locate your model's problem area by using Mechanica database ID numbers. ID numbers can be queried using the "Entity ID" macro in Mechanica Standalone.  The following ID numbers are associated with this error:  ######
    • The unconstrained degree of freedom can be seen by running a constrained Modal Analysis with rigid mode search. Animating the rigid modes will display the unconstrained degrees of freedom.  If the error still occurs, then the issue could be caused by material properties or unattached spring/mass idealizations.
