CST Studio LF transformer example needed

I am looking for an example or a step by step tutorial for setting up a low-frequency analysis of a typical switch-mode ferrite material transformer. I am, in particular, interested to extract core and copper losses in the results.

There are many examples of other types of problems with CST Studio but after searching for days on Google and YouTube I have not found one that involves this type of LF design to study.

Any help much appreciated.
