Shape of the average height functionAfter the DMTCS paper some measurements have been done regarding the shape of the average height function for rhombus tilings.
2d: The height function has been rescaled so that it is independent of system size. The measured results almost coincides for all examined system sizes. The measured results are also in close agreement with the analytical results for tilings of infinite size (H. Cohn, M. Larsen and J. Propp (1998), The Shape of a Typical Boxed Plane Partition, New York J. of Math. 4, 137).
3d: The height function has been rescaled so that it is independent of system size. It has been conjectured that the height function is flat in the unfrozen region. From the measurements shown above it looks like the height function is almost, but not quite, flat. If that is due to a thus far undiscovered measurement bug, or that the height function actually isn't quite flat, is unknown.
