where does wall boundary condition is defined?
i cant find wall BC in src.where it is defined?
I want to see how its impermeability is defined.
Wall is not a boundary condition, but an attribute to the patch. Please read the third paragraph in my previous post to you again:
A patch with the attribute "patch" can easily act as a wall, if you give noslip on velocity and zeroGradient on the pressure.
Furthermore, you keep posting similar questions in a lot of new threads. This will only results in a lot less searchable forum, so please modify your behaviour.
