Hello @shermama96,Have you described all the bodies as flexible or just 1 body? You may want to keep the component of interest (leadscrew) to be flexible and define rest of them as rigid(Geometry>Part>stiffness behaviour >rigid). Also, you will have to use fixed joints (instead of contacts) to connect rigid components together. The bed is too big, meshing that would be futile.Regards,Ishan.https://forum.ansys.com/discussion/comment/112124#Comment_112124

Thanks for getting back to me. I have tried switching between rigid and flexible to no avail. The plan is to model an entire CNC machine but I am starting with the simplest components just to get familiar with the solver. In theory I'd like everything to be flexible because I'll be using this model to establish geometric parameters for some of the cast components like the bed. For reference I'm not using any contacts for any parts, all bodies are coupled using joints.n
