I am building a model that has bolted joints. I have created three load steps (Perload, Fix & External Load). I am trying to run it on SOL600 for the first time as I have to do it in steps. When the solution type is choosen as Implicit Non-Linear (SOL600), in contact control paramers, by default it is checking the "Enable Initial conact". Is it required to do so? If so, do I need to pick bolt preload step Initial Contact Pair Loacase?
