This may sounds backwards but I'm attempting to create an analysis to show the relaxation/change in preloaded joints. I have a fastener preloaded in a structural analysis assumed to be at ambient temperature. I then want to run a thermal analysis using that as a pre condition to show, based on the material temperatures, how that preload changes at a specific temperature. I haven't been able to figure out how to make this work. I see I can use thermal analysis as a pre load to a structural analysis, but I can see how to do the reverse.
