When running PRO/III, how should we handle these three operating states?

I wonder how everyone handles these three operating states when simulating PRO/II? *** RUN STATISTICS STARTED 13:22:06 04/17/12 NO ERRORS FINISHED 13:22:08 04/17/12 2 WARNINGS RUN TIMES 4 MESSAGES What should we do regarding errors, warnings, and messages? Do you need to process it?

Check what the content is; if it’s related to process requirements or unimportant, you can ignore it. If different thermodynamic methods are used for two adjacent units, it will also issue a warning; you can ignore it.

There’s a message that says the following: ‘T1’ was skipped because all feeds are identical; the tray positions of the feeds, drawers, and heaters remain unchanged, and all specifications are the same as those in the previous solution. I’ve been thinking for a while; it must be because I clicked ‘Run’ twice, right?

Is there a circulating stream in your process? If there is circulation, the feed to T1 remains unchanged between the two calculations, so T1 is skipped.

There is no loop; I just clicked ‘Run’ once, and although everything converged and turned dark blue, I was worried that the calculation wasn’t complete, so I clicked ‘Run’ again, and that’s when this message appeared

Is it because I ran it thoroughly for the first time that he sent a message saying that T1 was skipped this time, since I didn’t change any of the conditions or logistics parameters – it was just due to running it twice in a row? I seem to have understood a little bit

This is clear: the program automatically ignores modules that do not require repeated calculation
