Hello John, Oliver,

Congratulations on an excellent Colloquium.

Could I ask, if Cheng Wang would be so kind as to share her notebook so that I may study her approach in more detail? I don't mind to reach out to her myself, but wanted to ask through this avenue first.

Oliver, I am progressing through your suggestion to my question posted during the session, to see the various boundary condition application examples. I may still have to ask you directly again. The problem I am considering is how one might prescribe boundary conditions for Natural convection driven flow "through" a domain. The simplest geometry would be a square domain where the vertical walls are heated and the horizontal are an inlet flow boundary on the underside and an outlet flow boundary on the upper side.

Thank you again, John Burgers.
