Abstract
We present the results of Monte Carlo simulations of the 3-D Heisenberg model with twisted boundary conditions. The boundaries are chosen to have a saturated magnetization in equal and opposite directions which imposes a twist on the order parameter profile centered at the midpoint of the sample. The magnetization profiles are distinct from mean field theory. We present a detailed examination of the magnetization profile and suggest experiments which can verify the finite size scaling forms we observe
