proporty of compressible fluid
 

Dear friends

I have one questions. I wanna use compressible fluid in my simulation but I don't know what the difference between thermophysicalProperties dictionary and transportProperties dictionary. can anyone help me about that?? when I use compressible solver, should I specify thermophysicalProperties dict?

I want to write density in a file, what is the function for export density in compressible flow solver?

Regards
