Aero app

It's a toy, Nothing more. It just generates some colorful dots on a screen

I'd agree with this assessment from a gut feeling. But it seems there are a lot of people (on this forum or in general) who are more interested in getting a colorful picture from CFD than meaningful, confident engineering data.

You nailed it.

As to the one who said that it's never good to simplify math.. I know of rockets, the ones who kill poeple with insane precision. They're basically inverted pendulum and the simplification sin(tita)=tita is made.. they still can land pretty much everywhere.

But perhaps you should also consider that just because a model is not accurate it may still be informative. For instance, many people think that putting a megaphone on the front of the car will help force more air into the engine. Someone who used this app in a thoughful fashion could probably see why it is no help.

That's a valid simplification for small angles though:
