Use leftclick-drag to move the grid/contour solutions.  Use shift-leftclick-drag to zoom in or out

Use rightclick to start streakline at pointer.     Use rightclick-drag to place an 11 point streakline rake.

Notes:

1) This program solves the inviscid Euler equations using the Beam-Warming, implicit euler algorithm. It is a finite difference model on a curvilinear mesh. Boundary conditions are explicit on all boundaries, including wake-cut, and with irrotational, isentropic extrapolation of properties to the solid wall.

3) Implicit 2nd order damping is included for convergence stability. Explicit 2nd and 4th order damping are included using the Jameson method.

4) The mesh itself is generated using either an algebraic method or with the GRAPE , elliptic Poisson equation method of Sorenson.  This method is highly non-linear and still occasionally bombs for cases of extreme grid stretching.  The only cure is to reduce the relaxation factor and/or reduce the number of grid iterations.  This will reduce the orthogonality of the resulting grid, but not greatly effect the solution.
