| E5025 | FATAL ERROR: E5025 | MPC AT GRID id COMPONENT n IS NOT PROPERLY DEFINED |
| Cause: | The specified multipoint constraint degree of freedom is not properly defined. The most likely cause of this error is multipoint constraint equations or rigid elements connected in a closed loop. All rigid elements are converted to multipoint constraint equations as they are processed. Dependent degrees of freedom that are independent in other multipoint constraint equations are rewritten and related back to a common independent degree of freedom. This error message results when that process fails. This error may also occur if a dependent degree of freedom is referenced more than once. | |
| Action: | Investigate the specified grid point and component number. Remove any closed loops that are the result of multipoint constraint equations and/or rigid elements connected improperly. Check for any multipoint constraint equations or rigid elements that reference the same dependent degree of freedom. | |
| Remarks: | None. |
