Hi all, this a re-post:
I'm doing a project for the university, and it's about the desing of a fired heaters type box with a horizontal tube convection section. Well, I'm trying to simulate this on ProII, but i have a problem. Everytime that i run the process, software gives to me an error, and its say that "run is not available because Unit Operations are incomplete". I went to the "help" menu, but there could find any solution, or any specification about the simulation.
