 Rjet really matters!!!!

 Here's the originating problem.data file for one of the runs (the only variable that changes is Rjet)

 The series of sims below is similar to the one that I sent yesterday with these exceptions: the opening angle of the Gaussian-tapered flow is 15 deg, not 45, and the structure of the ambient (environment) gas includes the torus in addition to the AGB wind.  In this case the outcomes of each of the Rjet sims is similar in shape but not in size.  Oddly, it is the Rjet=2 sim in which add behavior develops near the y axis.

 Comments on size:  The mass and momentum in the Rjet = 2 sim is 4x larger than that in the Rjet = 0.5 case, so the flow penetrates further as Rjet increases.  However, the odd knot that develops near the y axis -- combined with the fact that the flow barely encounters the torus on its lateral edge -- mean that the head of the flow spreads out laterally and accretes more ambient with time.  This slows it down.

 OVERALL CONCLUSIONS
 
-It seems from this that the sims with small Rjet (that is, a high degree of flow-surface pixelation) work well other than the jet width is determined by initial conditions and not the flow hydro.  For larger values of Rjet (that is, more diffuse momentum flux after launch) Rjet should be at least two (or the number of AMR refinement levels should be incremented by two) or else odd behaviors that develop at early times are amplified as the flow evolves will have a huge impact ont eh structure of the flow along its leading edge.
