We have been conducting our own attempt to validate Simulation CFD 2015 by modelling the well researched and documented NACA0012 aerofoil section in 2D. We have been very disappointed with our results and would be interested if anybody else has attempted a similar test. Following the advice in the Autodesk help files, we have the following settings:
Over a range of settings we have never achieved an error in lift force lower than 15%, and computed drag is typically 6x higher than published data for these conditions. I have seen considerably better results published on-line from Fluent and Cosmol simulations.
Is this really the best we can expect for this software, or am I doing something wrong ?
I have sent this also to Autodesk Support, with relevant files included.

Don't have much in external aerodynamics but I have few suggestions/questions...
Thanks.
I agree with OmkarJ on his third point regarding Y+ assement of the whole boundary layer enhancement region. Exactly my current problem !
The current display of Y+ appears to be designed for 3D representation, but in a 2D view there is some scope for improvement.
I've attached an imagine that may help explain my point.
