file types and heat transfer between two temperature air

Hi, all,

I am trying to find a description regarding SWFS file type, such as fld means result file, etc... Where are they?

And FS could solve two different temperature fluid mixing problem, but there is no example. I need to check heat transfer in solids box in physical feature even though I don't have any solid inside fluid region, just two fluid mixing together. Am I correct?

Thanks for help.
