However, when I directly connect the heat exchanger outlet to the collector inlet, the mass flow rate of the solar loop increases rapidly and reaches its maximum value.
Ali,I just did exactly as you described and it worked just fine here. See attached image. Please check your parameters and inputs carefully. Make sure you have a small timestep, and also consider adding pipes and the pump. Make sure you have enough flow on the other side of the heat exchanger to remove the heat from the collector. If you still cannot discover why it isn't working then I suggest you send your project to your distributor to see what they can find.
