Howdy People:

I am planning to map velocity field obtained from another flow solver as BCs for my openFOAM domain. For this I am using the externalCoupled boundary condition.

I would like to know what type of boundary type I should be using to support this kind of mapping, because in this case I have no definite "inlets" and "outlets", just a box where the velocity can change direction like winds. On the other hand, using the "wall" boundary condition will obviously not work.

Do I have to implement them as generic "patches"? If so, how?

Thanks in advance,
Gerry.
