I'm trying to model water flow onto a solar panel (via water outlets)(pic attached in post, the 8 things above the panel are the water outlets) and analyse its cooling effects. This is an external flow, and i understand to have stuff flow, i need to have lids and assign boundary conditions to them. Is this correct? Do i have to model the body of water too? if so, where do i need to do that and how? I have to define the flow rate of the water too btw. The version i'm using is SolidWorks Premium 2012 x64.
