Run of blast wave across magnetized wire up to late times

Attached - MPEG comparing density plots for runs with:

-Top, 10 T wire surface field

-Bottom, hydro

-The blast wave followed the behavior described in post aliao09082014; the density of the wire was 7.5 g/cc (80% Cu).

-Contours of the magnetic field strength are overlaid.

Key observations from the video:

-Before the rarefaction of the blast wave reaches the wire, i.e. before the peak ram pressure/density hits, the bow shock moves leeward monotonically. Once the ram pressure starts to decrease the bow shock relaxes windward.

-At early times, i.e. before the shock passes the center of the FOV, the contact discontinuity is visibly deflected by the magnetic field. At high latitudes with respect to the wire, this bowing out should be readily distinguishable from the hydro case regardless of possible projection or timing complications.

-At late times, the displacement of the nose of the bow shock in the magnetized run vis-a-vis the hydro run re-emerges after a long intermission where magnetic effects were suppressed due to the high sigma. At these late times, the ram pressure has dropped back down to low sigma regime.

-At late times, the dynamics of the near-wire region is dominated by the "ablation" of the most windward crescent of wire. The CD is visible in both runs to be between the "ablated" wire material and the wind. The dynamics of the runs are indistinguishable within this inner region.

-The wire temperature is set close to absolute zero, and the "ablation" at late times only spreads around cold, non-emitting matter in the inner region. Thus in both runs the inner region is not a significant source of emissions. I don't trust what the wire is doing at all here.
