Running magnetized wire problem with Peter Graham's blast wave

Previous runs of the magnetized wire problem used a uniform wind, Since early last month more realistic blast wave results have become available:

  1. Rise time of shock density-

10 ns for 1000 fold exponential increase with time from initial 0.01 mg/cc

  1. Decay time of rarefaction-

100 ns for 1000 fold exponential decay with time from the peak density of (1)

  1. Deceleration of the flow-

40 ns for 5 fold exponential decay with time from initial *150 km/s *This is already less than ½ of what Peter Graham starts with (>300 km/s)

The simulations w/; w/o B are running fairly slowly, much more so than what I've seen before. Before the rise phase of the blast wave passes completely by the wire we would be seeing times much later than what we've seen before.

Below: emissivity maps at 10 ns, separation between wire center and left boundary is 1.25 mm; the density peak of the blast wave has just emerged from the left boundary.

We should be able to see an effect on the flow from the magnetic field long before the bulk of the flow passes by the wire. If we can avoid going through the hump we can mitigate some of the effects of wire erosion and high sigma due to the large material flux.

Note: wire density in simulation is only 1% of copper, whatever erosion we see at later times are a gross overestimate.
