For the simulation of dimethyl ether, the simulation results of v7 do not converge. Can anyone help me? Solved This post was last edited by sufi on 2009-4-20 10:43 ]
Isn’t that the original poster? I downloaded it and ran it, and the result is convergent... It’s just that due to the existence of a loop, the tearing stream defined by aspen just doesn’t have an initial value, so it’s just a warning. It doesn’t matter, the result is valid after running. Just assign the result of your operation to the tearing stream as the initial value, and the warning will disappear.……
Thank you very much. "Just assign the result of your calculation to the tearing stream as the initial value" which stream does it refer to?
After looking at the order of the loop, I first assigned a value to flow stream 14, but the order of the loop changed. Then I assigned a value to flow stream 5. After running it, there was no change this time, and there was no warning, haha.
