Abstract: In this paper we study the finite size effects on the entropy of Villain model with ferromagnetic defects. We show how the entropy changes with decreasing concentration of negative bonds with large size. The entropy at zero defect concentration is known accurately. We aim to extrapolate results at finite defect concentration. The Pfaffian method is used to calculate the entropy.
