There is no built-in way I know of to import strain or displacement field results from an external source and then run a prestress-static analysis. I would call this sub-modelling. Ansys can do it. I think interpolating the field into the model might only be reasonable with h-element codes due to element-node mismatches. To do this you would have to runderstand the Ascii Creo files for a static run and make the solver think that it had been run in Creo.and use that study folder for pre-stress static. For example, run a simple arbitrary static analysis in creo, then go into the output files and replace/interpolate the resulting displacements to be what you want to use as the actual pre-stress. Anyway, many things can be done but are not practical. An idea would be to see if you could get a chatbot to write some python code to do the trick, if it can be made to understand the ascii file format. I just this week started messing with our company version of chatgp and its pretty good at python. I had it write me an equivalent of creo purge command with the choice of keeping more than just the last numbered file , recursive through folders, and it only needed a tiny bit of coaxing to get it right!
Here is an article that references the Ascii file format if you care to start down that road.
