    1919* The inputs in the data files are given above, however, visualization in Visit seems to show both of these values less by 0.5.

     21Here are some stills of the initial conditions. First is the first frame showing the mesh,

     25Here is just the density at this first frame, the legend is in particles/cc:

    2333Here is a movie of the density, with field vectors overlaid. The field starts with a Beta=0.5 everywhere in the box. We see early on the NTSI develops and grows for the first 20 frames or so. By about 2 Myr, it seems the NTSI begins to collapse back toward the midplane. Without the troughs of the NTSI for the material to funnel toward, the material is instead splashed laterally in the y-direction. This creates large shear that excites KH modes especially at the tops and bottoms of the colliding streams. The first core (sink particle) forms late in the simulation, by 15 Myr. Peak densities are ~12,000 /cc < H2 densities.
