WARNING: The calculated feed temperature for the hot side (3.5900193D+02) is inconsistent with its inlet stream value (3.5863857D+02). Possible cause: loose flash tolerance, or an upstream block with different NPHASE or PROP settings. The calculated value will be used in calculations. Adjusting the convergence tolerance didn’t help, and the inlet temperature of the heat flow was not entered either; please advise

Check the input values; usually, it is an incorrect value that causes the calculation conflict.

The inlet temperatures of the hot and cold streams in the heat exchanger are not entered; ASPEN calculates them automatically. .

The input values for the entire process, well, the heat exchanger is determined based on those calculations
