Why can't a study with errors be solved?
You cannot solve studies containing some serious issues with the study inputs.
Possible solutions
Click Repair next to the desired study in the Solve dialog box. A message box lists issues that need to be addressed before solving the simulation.
Note: You can also click the Pre-check command from the Solve drop-down menu to display the warnings dialog box. More information about what may be missing should be listed. A quick check of constraints, loads, and contacts may fix the issue.
