We describe results of Monte Carlo simulations on a model that seems to have the necessary ingredients to describe a disordered type-II superconductor in a magnetic field. We compute the free energy cost to twist the direction of the phase of the condensate and analyze the results by finite-size scaling. The results show convincingly that the model has different behavior as a function of dimension: in $d=4$ the model clearly has a finite transition temperature; $T_c$, while for $d=2$ only there is only a transition at $T=0$.
