Barry,
Notwithstanding Posts 10 and 11 which I think should be looked into (why is a surface on the plane of symmetry being layered?) I decided to start a clean sheet of paper for this mesh (sorry, if post 10 and 11 are to be looked into, you have the only copy of the project that still includes that meshing operation).
I deleted all my meshes and simulations from the project and only left the best geometry.
Then I used some meshing guidelines that I have been developing with Darrens help on another topic and which can be found here.
The results seem nothing less than spectacular so far (copy the project again if you wish), here is the y=-60 clip of ‘Mesh 1-4,685,530v 95.2 percent Inflated 40x20x26’:
I am simulating it now for a look at yPlus range but I expect good results with a 95.2% weighted inflation factor.
Keep your fingers crossed 
Dale
