Hi.. I am beginner in CFD and I want to know how to simulate heat flows in the buildings, buoyancy effect of natural ventilation in the building with a side opening and a stack. Can somebody help me on this????

Create a domain of ur interest with 4 walls, side ventilation etc.

Define the known temperatures at each wall of the domain, give proper air ventilation BC's and switch on gravity to simulate buoyancy effect that accounts for natural convection. if u r more specific on ur requirements, I can answer u better.
