cyclicAMI issue for infinitely long circular cylinder

I am trying to simulate flow around a circular cylinder.
To mimic infinitely long span, I want to use periodic BC on the two sides spanwise (span length is 8 and origin is located in the center of the cylinder).
mesh was made by cfMesh so cyclicAMI instead of cyclic type is used.
boundary patches are as follows:
inlet (in flow direction, -x)
outlet (in flow direction, +x)
top (in cross flow direction, +y)
bottom (in cross flow direction, -y)
side1 (in spanwise, -z)
side2 (in spanwise, +z)
so in polyMesh/boundary, I applied cyclicAMI as follows:
separationVector (0 0 8);
separationVector (0 0 -8);
assuming laminar flow, I applied cyclicAMI to 0/U and 0/p as follows:
fixing typo and separationVector sign get to work.
