I don't know exactly but the difference might be that in the isotropic case the magnitude of the basis vectors are the same while it is not for the anisotropic case.

I got the results. the only mistake I was making is to use anisotropic lattice instead of square lattice.
what is difference in anisotropic lattice with L=2 W=2 and square lattice with L=2.
