You are an absolute G for this one. Mic quality: COD lobby. Explainations: God teir. Thank you for this epic video now i can finally solve for areodynamics of a cow with my $1000 dollar peice of software
Overall great to see helping others get up to speed on CFD. Be careful with assigning Compressible on the Solve dialog - Given that you've assigned your fluid as Air[Fixed] we are not taking compressibility effects in to account. And given that this is a small RC plane at 40mph for many design aspects we could assume it negligible and just run Incompressible. We do have a great outline for doing external compressible air flow in the Help , accessible from the Start&Learn tab, which can also outline meshing best practices. Otherwise nice walk through and keep up the work
Great tutorial, only thing is that for accurate results, you shouldn't just run a set number of iterations, you should keep running iterations until all of the lines are flat (converged), otherwise you will get inaccurate results, but on the whole, great tutorial, without it I wouldn't know how to use cfd, which helped me and my team a lot in f1 in schools.
A question: should i use the shell command in constructing the box or just a solid body? I've seen a user raised this concern in the comments but apparently your comment is hidden/not shown... Thanks for the great video though!
I ran a test for a small car I'm designing and the results showed forces or roughly expected magnitudes but the resultant forces showed as negative. Have I made an error or can the negative sign be ignored?
Hi, Nice tutorial. I'm using Solidworks to import my model into Autodesk CFD. The box does not turn into an outline when the option is selected. It still remains as a solid. I tried this both ways by importing as a STEP file and the ASSY file. Any suggestions? Thanks
I love your video ! thank you so much ! but im having this weird problem on a simulation of a sleek drone chassis I put together , the forces are just... not realistic with lift (without any airfoils on an almost 10 cm long model) reaching 10^11 N , the flow pattern is also pretty wonky, any ideas ?
@@Shasty8817 damn that was a fast response ! I figured it out actually, apparently It was starting after the iterations ? ya I have no idea why or how but setting it to start from 0 completely fixed it
Thanks for this tutorial. It was really helpful. But I got a problem. I have done this with an airfoil instead of a whole airplane and I get 30 kN (400 iterations, 18 mph), but you only get 2.5 N. Why does this happen?

Hello, could you make a video about creating the boundaries/box. I made one, and I made is as a "new body" and when I import to CFD, I only have the box. I also export as a .step, but my model just isn't inside when I try to simulate. Could you help me? Thank you!
I am testing an rc plane but it has only 2.2N of lift at 20km/h but my plane weights 2kg will it fly at that speed please? help me out Also I have a motor that can generate 5kg of thurst how can I add that to my CFD test? One more question How can I turn thrust value to air speed? Thank you all in advance.
Hello, I was wondering how this plane only had 2.5 N of drag (or FZ), or less than 1/4 of a kg of upward force. Is the simulator 1) calling FZ, something different than the upward force or 2) taking the weight of the plane into account? Could someone please clarify this for me ? Thanks
Hi, I'm not sure why all my comments got deleted, but you should just be able to extrude a box in Fusion 360, by just creating a new component (It needs to be its own separate component!). Set its dimensions and position carefully, it will become the wind tunnel (at least that's what you should select).
@@Shasty8817 Thank you... This is what went wrong... I was making a fairly basic version of a windmill,so as with other initial designs I used form tool to extrude line components instead of profiles (hence creating bodies without thickness)... That is why it was not exported to Autodesk CFD
@@Shasty8817 I'm pretending to simulate how the chine influence in the flight for different angles of attack and speed (cruise, take off and landing) and maybe for different altitude (air density). I think it's a very complicated process and I don't know exactly how to start. I want check mainly the lift and drag increase for those different scenarios.

man was born to simulate everything just to "see what happens"
happy simulating! also don't forget to turn off the compressible flow haha
Mic quality is so real

Very good tutorial! You even explained how to export from your CAD, thanks a lot!
Informative and straight to the point. Thank you for the amazing tutorial!
thanks! it helped me simulating the water flow for an hydrofoil :)
you totally forgot to set your other walls to slip, otherwise, they will greatly influence the flows, especially when they are so close to your model.
What is the box made of? Is it a sketch, a form or a body? Or does it work in all of them?
Where we find Coefficent Drag & Lift?
Thanks a lot! You are a lifesaver.
Hello, how do I make a transparent box like this one I made in Fusion 360
A question: should i use the shell command in constructing the box or just a solid body? I've seen a user raised this concern in the comments but apparently your comment is hidden/not shown... Thanks for the great video though!
I think a solid body (make sure it is its own component) in Fusion 360 should be sufficient. Let me know if it works!
Thanks for the tutorial :D
very well done, really helped me out
Thanks! This was really helpful
He man the CFD is not opening in my pc please help me.
Podrias hacer un video explicando como ensamblas y armas el modelo antes de simularlo?
could you tell me how to make the outer box in inventor ??

@@Shasty8817 Figured it out. In the geometric tools option, we can create our own box in CFD. This creates a box around the model automatically.

try to do it as a new component, and have the rest of your model as components as well. lmk if that works
If FY is refer to Drag force, does FZ refer to Lift Force ?
excelente tutorial amigo
TYSM 👍
Awesome beginner tutorial.
How did you get your hands on this software? It's "call for pricing" on their website... :-/
Thank you so much. Could you explain how to find the overall drag and lift generated?
from 10:04, it is at the bottom.
I am testing an rc plane but it has only 2.2N of lift at 20km/h but my plane weights 2kg will it fly at that speed please? help me out

One more question How can I turn thrust value to air speed?
Thank you all in advance.
why did you put cero pressure at the back?
it keeps telling me assertion failed when pressing select all in wall calculator
IDK why but this isn't working for me , CFD keeps on crashing when I load the file, there some thing wrong with my model
once i open CFD it zooms automatically without stoping.. how to stop this
can i calculate the coefficient of drag with this?
@@Shasty8817 oh sorry, i must have missed that. Thanks for the fast answer

The airspeed is set to just 40mph..
sorry how did you do the box in fusion? do u mean like i just extrude out a rectangle?

Set its dimensions and position carefully, it will become the wind tunnel (at least that's what you should select).
Make it solid, no need to shell it or use the surface editor. Just a simple rectangle + extrude (MAKE SURE IT IS A COMPONENT SEPERATE FROM THE PLANE)
@@Shasty8817 ok that makes sense now. I was trying to hollow it. Thanks so much
Isn’t it better to run it on the graphics card?
thanks for sharing
Give link for geometry and design of these model
I'd be glad to send over the designs if you send over an email to shihaocao@gmail.com
Hey..when I export my model from fusion to cfd...all components are exported as a single component...what to do?
@@Shasty8817 yes sir
Should the tunnel be a whole body or should i use shell tool on it?

Can you do a drone CFD testing?? I really need it .
Yes you can use autodesk CFD to do drone testing
Why do they have to make the orbit thing so fucked up!?
the box is hollow right..?
you need not CAD it that way, but it will become hollow in the sim
@@Shasty8817 nvm i figured it out this is so cool
ive been mkaing it hollow but it kept glitching up i thought thats what u were gonna use as boundreis and put air in between
