Allowable Errors
In most cases, Creo Simulate does not start a run if it finds errors. There are a few errors that do not prevent a run from starting, including:
loads, constraints, heat loads, prescribed temperatures, and convection conditions that result in singularities
elements that should be linked
gravity loads that have no effect
For more information on allowable errors, see Check Model.
