For the model I am currently working on, I need a laminar flow boundary condition in which the pressure gradient remains zero along the length of the surface. Is it possible to create my own BCs or am I stuck with the predefined ones?

Hi

you can use the additional weak conditions at will to add everything you can express in vali equations ;)

(you might need to turn on the Preferences - show "Advanced Physics interface options"

Good luck
