At runtime, it always shows that some flow elements are defined repeatedly or their flow value is less than or equal to zero; these flow elements cannot be seen in the flowchart. Thank you! *** Error *** Stream ‘s4_r1’ has invalid compositions that are specified to be less than or equal to zero. .
Has it been a problem all along, or did it appear recently? Could it be a version issue?
Carefully check the process; problems can arise if it isn’t set up properly. What the moderator said applies as well – you might try exporting the file and then importing it again. . .

Reply to 1#: With too many additions/deletions of stream stocks in Dongfeng, this issue can occur; it can be resolved using the following method: use the Export option under the File menu to save it as an.inp file； Then import it back in. If there are still issues, you can delete the relevant stream information from the stream section in the .inp file, save the file, and then re-import it using import.
Thank you, I changed to another version; it’s fine now.
