An open tank with 3 pipes work as feeders for a time dependent heating process of water through a circulation process with a heat pump. I would like to simulate this process by implementing a Comsol Multiphysics 4.3b version. I know in advance that the flow is in the Laminar region within the tank but it is in the Turbulent zone through pipes. I implemented the Nonisothermal flow module/Laminar interface. I had a problem with the outcome especially with the mass flow rate of water which I used at the inlet. I need to couple the model with Nonisothermal Flow/Turbulent interface for the feeders and a Laminar flow for the tank. How can I manage that?
Your reply is a well appreciated.

It should be very easy, because you may upload different physics and apply them at the domains you want simply by selecting.
I'll try a similar problem in few days.
Hi Michael,
Thank you so much for your advice. In fact, I have a problem with the boundary conditions when coupling the Nonisothermal flow in pipes (Turbulent Flow) with the Nonisothermal flow inside the tank (Laminar flow). I am using 4.3b version which I think needs some consideration for stating the velocity and pressure at the interface between the pipe and tank connection.
Your help is a well appreciated

Hello,
It easy to use the same velocity at the interface region and different physics.
Best wishes
