Re: About ConvectionBC

[steed188]

By thousands of check, I found why my convection BC didn’t work finally！！！ 😀

I chose Local Boundary condition so that the bc didn’t work. If I chose Interp bc it worked!
May I asked the meaning of this two kinds of bc?

By the way, as you said that I should use flux functor to calculate uAv every time step, I found that all of the flux functors are based on a circle shape, though my outlet is a rectangle. Is there a functor that can be used for rectangle shape?

My temporary solution is that defining a circle in the rectangle and using flux functor to calculate the uAv. Although it can be calculated but I’ve no idea whether it is correct.
