- Near critical evolution (0.5 MB).
- Zooming in at critical time on above solution (0.3 MB).
- Monopole (0.3 MB) pair collapse in a different model (easily adapted from NLSM code).

- Movie of near-critical chi (z=0 slice). Any self-similarity demonstrated by the solution is not clear in this movie because it's hard to see the dynamics on the various scales. However, the following demonstrates it more clearly at the expense of cutting out much of the data.
- Movie of near-critical chi. Here, an x=0, y=0, z>=0 cut is shown versus log(r). This is analogous to such plots done with explicitly spherically symmetric adaptive codes. The solution shows the familiar self-similar behavior chi(r/t).
- Movie of chi with bounding boxes on the various grids (z=0 slice).
- Movie of the near-critical energy density (z=0 slice).

One other thing about the above. In this nlsm model, I use a generalized hedgehog ansatz which requires somewhere that the field goes to zero. I fix the field to be zero at the origin, and that's why you see the zero point at the origin in the above.
