Dear all.
I want to creat cyclic boundary using a pair of patches in lateral.
I want to do channel flow simulation, my wind comes from left.
So I think my cyclic boundary should be translational, not rotational.
But I don't know the meaning of separationVector , how should I set this vector when generating cyclic boundary . who can give me a explanation, Thanks.

// Name of new patch
name CYCLIC;
// Type of new patch
type cyclic;
transform translational;
separationVector (0 1 0);
constructFrom patches;
