Dear CFD online members,

I have an idea that I haven't successfully brought it into a simulation yet.
There are three parts in a same region having 1 inlet and 2 outlets in my simulation model (using STAR CCM+ software). However, the fluid domain is necessarily simplified to reduce the simulation time so three parts become 2 parts. The removed part is simplified into one inlet and one outlet with an interpolation function of pressure and flow rate (e.g. pressure drop = f(mass flow rate)). The output of this simulation is to evaluate cooling solution of coolant over a water jacket.
Since I remove one parts in my model, now it has 2 inlets and 3 outlets.
Of course, the new inlet and outlet has same flow rate. Is it possible to set up the boundary condition for the inlet and outlet of the removed parts with the relationship of flow rate and pressure drop?
I have searched as much as possible about manual and internet, but have no answer for it. Some texts call this problems be "coupled boundary" or "conjugate boundary". If you have experience about this sort of problem, please give me some advices. Thank you in advance.

Best regards,
Marcus
