Fluid pkg transition occurs in the ASPEN HYSYS FCC main fractionation column simulation
Thread Content
In the ASPEN hysys simulation, only one fluid package was set, using the Peng-Robinson equation. As soon as towers were added on the main workflow page, the message “Fluid Pkg Transition-not solved” appeared, along with “FluidPkgTransitionObject-solved”. I’ve seen people on forums encounter this problem as well; it’s said that the parameters for converting between fluid packages before and after using CUTTER aren’t set properly, but I’m not using Stream Cutter at all Please ask an expert to help answer
After adding a distillation column, on the distillation column definition page, a message stating “Fluid Pkg Transition-not solved” appears each time a new stream is added. How can this be resolved? I’m a beginner in urgent need of help; thank you all for your assistance
I found that when a fully defined stream is added to the distillation column, the \"Fluid Pkg Transition-not solved\" message does not appear; however, this message shows up when an undefined stream is added. I’m not sure if this is the reason
