why doesn't the total mass increase when using buoyantPimpleFoam
 

Hello, guys, I am using buoyantPimpleFoam to simulate the air inflation progress. I have a model with one inlet patch and other walls. Air is inflated through inlet and we know that the temperature and pressure will increase, like we inflate a tire, but in buoyantPimpleFoam there aren't any changes in related to temperature and pressure in the system. Is buoyantPimpleFoam actually suited for incompresible fluid, which conflicts with description of user guide.
