Need Help Conducting a Stress Analysis on my Project


This is a follow up to my previous questions dealing with my Mechanical Closure Device project in CATIA. Now that I have constrained the assembly and assigned joints, I would like to perform a stress analysis to determine the relationship between the actuator and the door. I have assigned the connections and would like to calculate the stress. However, every time I press the compute button, I either get errors regarding the mesh or errors regarding singularity.

Attached are two CATIA files, the original assembly file with the joints and the general structural analysis file.
