the model created seems not to behave phisically correct: heat exchanger reduces both temperature of TL and moisture air.
it should heat up air, cooling down fluid instead.

That was a mistake I have corrected the day before yesterday with positive results. not it converges rapidly without issues. I am now moving to a TL_2P_MA system

Setting reasonable parameters to discribe the nominal conditions for the heat exchanger seem to resolve the issue. Pay particular attention to units and type of information needed (mass flow vs. volumetric flow). The port size matters as well because the local velocity calculated based on port size and mass flow is also part of the energy flow calculation.
