The bolt shank is in the threaded hole. Use the plane of the part where the bolt emerges from the threaded hole to split the face of the bolt shank. Then the face that is inside the hole can be bonded to the hole and that will prevent it from moving.&nbsp; The underside of the head of the bolt will be bonded to the face that it is touching.&nbsp; The cylindrical face of the bolt shank between the head and the split line at the threaded hole is where the bolt preload is applied. During the solution, Ansys will split the mesh at the center of the bolt shank and put constraints like a translation joint that will pull the two halves of the shank toward each other using the preload force in step 1, then hold that displacement fixed in step 2. That force will cause the bolt shank to become slightly shorter and the other part will compress the two legs together.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-388205","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Ashish provided a good description that I can explain a bit further.
