WebApr 1, 2010 · ansysfreak (Civil/Environmental) 1 Apr 10 06:29 Dear Under the analyse setting you need to define 2 loadstep. Then look at the details of the bolt-pretension, a table will be availeble, load the pretension in the first loadstep a lock him in the second one, then go the the forces and set the force in the first loastep to 0. Regards WebI am simulating a butterfly valve There are three bolts in the top and three bolts in the bottom I have defined bolt pretension by creating a new coordinate system for the bolt stem and assigned that to that particular bolt. In the same way, bolt pretension is created for all the 6 bolts separately.
