Hello everyone!

I'm trying to implement a boundary condition for a surface by using CodesFixedValue.

I have the ground surface, and i want to calculate the velocity for this patch from the velocity and the z coordinate of its neighbour cell.

i have known that we can get the z component of the neighbour cell by :

z(this->patch().Cn().component(vector::Z))

However for the velocity i haven't figured out yet.

Could you please give me a hint?

Thanks,
