Hi,

I don't understand how to create the BC, with OpenFOAM, at the inlet level of the open channel?

inlet

INLET : $\frac{\partial w}{\partial z}=0, u=0 , \Theta=0 , Pm=-0.5U^{2}$

RIGHT(black) : adiabatic; $\Theta=0$

LEFT : (red=hot) $\frac{\partial \Theta}{\partial x}=-1, u=w=0 ,\frac{\partial Pm}{\partial x}=0$

OUTLET : $\frac{\partial u}{\partial z}=\frac{\partial w}{\partial z}=0, \frac{\partial \Theta}{\partial z}=0 , Pm=0$

Thank you .:)
