+~~~~~~~~~~~
+* large domain with airfoil section near centre
+* extremely non-orthogonal, highly skew mesh refined around the airfoil
+* running at Mach 1.78
+* limited corrected 0.5 on all laplacianSchemes because the mesh is so poor
+* run to t = 0.02 with nextWrite; change to stopAt endTime to continue running
+* deltaT can be increased later in the run to 2e-07
