  Simulating superfluid turbulence using the localized induction approximation
in periodic bound- aries produces open-orbit vortices, which make superfluid
turbulence unsustainable. Calculating with the fully nonlocal Biot-Savart law
prevents the open-orbit state from forming, but also in- creases computation
time. We use a truncated Biot-Savart integral to investigate the effects of
nonlocality on homogeneous turbulence. We find that including the nonlocal
interaction up to the average intervortex spacing prevents this open-orbit
state from forming, yielding an accurate model of homogeneous superfluid
turbulence with less computation time.
