defineUBouzidi is not a method of the super lattice but a free function that accepts the super lattice (sLatticeOne resp. sLatticeTwo in your case) as its first argument.

So this should look something like (I can not ensure that this works in this way exactly as I do not know your whole code):

defineUBouzidi(sLatticeOne, superGeometry, 5, poiseuilleU);
defineUBouzidi(sLatticeTwo, superGeometry, 5, poiseuilleU);
