I’m trying to simulate indoor velocity to explore the performance of an adaptive facade responding to outdoor wind speed. I want to simulate the change in indoor wind speed with air vents on both sides and on one side. So the question is, how do I set inlet and outlet air vents so that the snappyhexmesh can around the entire building? I tried two methods, but neither seemed to work very well:
- The inner and outer layers of the DSF were set as inlet air vent (blue triangle) and outlet (red triangle) . However, the snappyhexmesh was only around DSF.
- On the basis of method 1, expand the calculation area to the whole building (green part). The snappyhexmesh didn’t around DSF.
I appreciate it if you can help me to solve indoor air flow with DSF using butterfly CFD.
