The Aspen Plus manuals show a Unit Operation Block for HeatX: two-stream heat exchanger (Unit Operation Models, p. 3-5) which does not seem to require an initial guess by the user. Also in the Chapter, Convergence, Using Initial Guesses is discussed only with recycle streams (Aspen Plus User Guide, p. 17-1).

Problem Statement
Counter-current flow (neglect pressure drops)
Inlet 1: heat transfer fluid (Biphenyl, C12H10, MW: 154.211, CAS: 92-52-4), 0.5 MPa, 160 C, unknown flow rate
Outlet 1: heat transfer fluid, 0.5 MPa, 135 C
Inlet 2: water, 0.2 MPa, 25 C, 42.5 kmol/h
Outlet 2; water, 0.2 MPa, 125 C

Thanks for a solution or any advice.

PS: I found the solution by trial and error, but I would rather the computer perform this tedious task.
