Best CFD CAD software
What are the best CAD applications (i.e. online calculators and exe. programs) for propeller, wing , tail, fuselage and flight control surfaces airfoil and 3D CFD?
Some of what I got so far:
ANSYS (e.g. ANSYS Fluent)

The best CFD software packages are usually the ones where the user knows what the limitations of them are. Until you educate yourself about physics in general and fluid dynamics in particular, all of them are pretty useless. Garbage in = garbage out and all that.
Having said that, I play with my own Excel spreadsheets and XFLR5 for airframe design and at the moment I'm learning to use OpenFOAM for 3D CFD, but it's all been several years of reading and study and I wouldn't say any of what I have done till now is definitive, although it's been challenging and fun.
The first question you need to address is, what do you need it for...?

CFD and FEA programs are really neat. But, they take a lot of time to figure out how to use them for complex problems, even with an advanced engineering degree.
If you are going to use them for simpler problems they are overkill. Yeah, they will do the job, but, you can get the same answer faster with simpler calculations.

you left out OpenFOAM / Blender
Here is a short video of it being used -
And Blender running an airfoil -
If your not running your own Beowulf cluster or have access to one, Amazon cloud rents cheap on the spot market.
