Inviscid shock interactions on double-wedge geometries.

As suggested by Graham Candler, we examine some steady (?) flows involving a double wedge in high Mach number flows. In particular, we deomnstrate that the GFM is an adequate technique when such features as triple points are of interest. As a basis of comparison, we use the parametric study by Olejniczak, Wright and Candler (JFM 1997).
