Hi foamers,

I am simulating a 2-D jet with buoyantBoussinesqSimpleFoam. I have referred to hotRoom in tutorials but I am still trouble in setting boundary conditions.


1. what does the alphat mean and how to set it in walls, inlet and oulet?

2. How to set p_rgh in walls, inlet and outlet?

3. What does the setFields mean and do I need to setFields for my case?

4. What does the reference temperature mean in transportProperties?


Here are the boundary conditions that I set, but it can not work at all.
I am new in openfoam, any helps are welcomed.
