inlet and outlet condition for a simple model
 

Hi folks,

It might look weird but i have a doubt on inlet and outlet condition inputs. The scenario is i have 3 inlet where fans are placed having mass flow rate of 0.1 kg/s each and 4 outlet where 4 fans are placed and have same mass flow rate each. How to provide boundary condition? Kindly guide.

Thanks

Use mass flow for all except set one outlet set to pressure. The mass flow of that one will of course be set to the remainder by conservation of mass.
