How can TRNSYS calculate direct and diffuse solar radiation given an average global radiation?

I am doing a simulation based on an experimental module and I have an average hourly global radiation but I need at least to estimate the diffuse portion of it or direct radiation for my specific station. I read that TRNSYS can calculate direct and diffuse solar. But I don't know how.
