Hello, I am doing a lifiitng analysis for a machine. The machine is having all beam connections. I have created a coordinate system from where the lifting will be done and created body-ground spring from there. I have applied gravity downward, and want to do the analysis with weak spring turned off. but i am getting below error, i have checked all the connections, it looks good. I have tried same analysis by fixing the lifting hook, there it is running fine but with the springs it is showing below error. i gave the spring stiffness but showing the below error. please help me with this.

Hey,

The error suggests that there is some body which is going through rigid body motion or some contact is missing or not set up properly. I would suggest you to check initial contact information and also double check your setup. If you need more help on that you can post some snipshots which would help the forum members to check your setup.
