A++, given all conditions of the cold fluid, is it necessary to enter the flow rate of the hot fluid? ! For Aspen Plus (not EDR), it seems to be necessary. Is there any way to specify only the parameters of one fluid, and let the software calculate the flow rate for the other fluid? ! Thank you.

There’s no good solution; adding a calculation module can achieve what you mentioned

It’s about writing code in the calculation module: first calculate Q, then set an initial temperature; use CMt to determine the outlet temperature, and use KAdT to calculate Q1. Keep adjusting the inlet temperature until Q and Q1 are equal

Oh, using Fortran?

Can HYSYS calculate it directly?
