Hei,

I have done some pressure measurements in two buildings and I want to compare my simulation with the measurements.
I could only measure differential pressure between windward and leeward facade, so I was actually wondering how can I get the same from the simulation. Can i just get the difference between windward and leeward side from OpenFOAM? I know that on incompressible flow I get the p/rho and that I can also add the reference pressure, but the difference would still be the same.
So, when I have a positive pressure on the windward and a negative on the leeward, is it correct to assume that the differential pressure (to compare with the measured differential) can be calculated by substracting one from the other?
Any advice? Thanks
