No problem Ji. If I'm not mistaken, you're simulating the whole screwing process so the pre-load is expected to be developed in the screw as an outcome of the simulation, but if you're interested about the bolt pre-tension object in Ansys Mechanical, please check the following document: https://innovationspace.ansys.com/courses/wp-content/uploads/2020/10/2.2.3_Bolt-Pretension-Object_new_brand.pdf
