Programming in OpenFOAM: writing a Custom Boundary Condition

In this video, we will show how to implement a new boundary condition step by step in OpenFOAM. If you need to develop a new boundary condition in OpenFOAM, I would definitely recommend seeing this video. The fluid flow in a rectangular channel (Hagen-Poiseuille flow) is investigated in two different conditions: 1- A constant velocity profile at the inlet 2- A fully developed velocity profile imposed at the inlet of the channel For the second test case, we have written the parabolic velocity boundary condition employing “codedFixedvalue” in OpenFOAM.
