In reality the fluid (the air) is flowing along your airplane depending on the wind direction from different angles. So you can say the half of the plane has not the same coefficients as the full body because you have to rotate the airplane in the flowing fluid. Just a little bit side wind and the second half is necessary to get the correct coefficients of drag. For very simpelized cases in CFD you can come to the result of same coefficients. If you want, you can figure it out by creating an easy example with a ball in CFD. You only have to make the correct setup.
Hi quick question. I am at the point where I get my drag and pressure graphs and when I am in the contour options it wont let me see the inernal boundary conditions and therfore wont let me select the contour of my plane/wing part. I cant see the interior air either so what can I be doing wrong. I would really like contour of the wing.
Greetings, how was the geometry of the plane designed? Is it using the Insight program or another program was used, kindly I need a video of how to design the plane
Thank u for this video. I have a problem. I did as you did but ' cl cd cm ' values were calculated incorrectly. Do you have any idea about this problem?
some thoughts. it is not clear whether you have accomplished anything, here. it is not clear whether the velocity has been set too low --- there appears to be, essentially, NO lift or turbulence, predicted. it is not clear whether the program has treated the aircraft as being FIXED in space. it can be understood that a simulation of air flow past an airframe is not IDENTICAL to what happens, When an airframe Moves through air. clearly, the asymmetrically shaped nose WILL produce nose-Down moment, in flight. since this design has no real fuselage, you have NO fuselage-related data. the design of the stabs is less-than Normal/optimal. cheers googletranslate
It's is our first video regarding CFD analysis so we thought it should not be complicated to the followers to understand . So we have done it with basic design . On our next video on CFD the complete design will be covered and process of simulation will be detaily explained. Thanks for your suggestions.
Hello this a good video. But I want to ask that the model imported to geometry is just a shell? Or could i import a model with full solid or structure inside?
the enclosure is a joke, particularly that you chose to keep the faces adjacent to the wingtips as wall and not symmetry or an outlet. You only end up getting exaggerated results owing to narrowed enclosure around the model.
Вот ответь мне на вопрос , зачем тебе ансис , если ты построил самую плохую модель из всех возможных, с большими потерями на балансировку и большой омываемой поверхностью ? Линии посмотреть ? Или кнопочки понажимать ? Ты абсолютно не умеешь пользоваться этой программой и не обладаешь базовыми знаниями и опытом .
Can you Explain how we can get Stability and Control Derivatives for Different angle of attack, slide slip angle, and mach number.
what if you analyse half of the geometry? would the coefficients of drag and lift be the same?

Super video bro
Why does the drag coefficient is negative?
Machine?

could you upload the cad of the Rc plane
Why is the enclosure so small? What should be the proportion between the virtual wind tunnel (enclosure) and the model be?
How to find vortex flow brother...

I think your calculations are wrong ,too.
It's wrong perhaps because he didn't specify reference values, and the domain contains contact regions...
Geometry???

You can import a model that isn't a shell
drag valus is illogical and the solution has not converged
