Autodesk Simulation Mechanical Accuracy

[PJ18]

I am reviewing an FEA performed by a third party using Autodesk Simulation Mechanical. Within the program I am most familiar with (ANSYS) convergence is used to ensure an accurate result of the von Mises stress. Simulation Mechanical does not seem to have a similar tool so I would like to ask how the results can be assured to be accurate. The autodesk website states that mesh convergence is partially automated but this doesn't confirm to me that an FEA will be accurate automatically using this program. Can anyone shed light on the automatic convergence or accuracy of the program?
