Custom Boundary Condition


I would like to define a boundary condition through a screen. I already know the flow through a screen is a function of differential pressure. Is there a way to define the velocity out as a function of pressure?


Hi @dhamilton!

As far as I know there is no possibility to define that with custom boundary conditions as you either prescribe velocity or pressure but not both at the same time. @1318980 & @Get_Barried, can you confirm this? Maybe I missed the question.




Hey everyone,

Not 100% sure but I think you are correct Joseuf. I’m not too sure if you can define velocity out as a function of pressure through some formulation via the “custom” BC. Maybe Darren might shed more light on this.
