In this tutorial, we will learn how to set up a simple CFD simulation case for flow over a car. In this tutorial, the procedure of geometry preparation, meshing, setting up boundary conditions, and viewing the results is demonstrated.

Thank you! I've subscribed, so I'm definitely waiting for more content like this :D
Welcome aboard! More content is surely going to come up. Keep sharing and supporting.
BRO YOU ARE AMAZING, I used this video for the airflow around a human. This vid worked wonders. Thanks so much!!!
Fantastic! That's really great. Keep sharing and supporting.
Owww...thank you so much. After seeing a lot of videos finally i have seen your video and done the simulation by myself for the 1st time and i am so excited.
Thanks a lot and want to see a videos about drag reduction by using spoiler and shark fin...
Thank you again
Glad to hear that the video was so helpful. I will definitely try to work on your suggestion videos in near future. Keep sharing and supporting.
the best explained video so far, much appreciated brother
Glad it helped.
Desde Arequipa-Perú : gracias no sabia como hacer este problema toma tu like y tu campana
Thank bro it helped me a lot for my project
Thanks man so much helpful thank you so much for making this it help me a lot
Thank you so much for this tutorial!!!
Most welcome. Glad you found it helpful. Keep sharing and supporting.
Thank You for nice CFD Video. Good for beginners
Hey! Thank you for the detailed tutorial! May i ask which type of Honda is the one using in here?
thanks! really comprehensive
Hello. I am glad you liked the video and found it helpful. Keep sharing and supporting.
Many thanks to you!
very helpful;; thanks a lot
Very well explained. 😁
Glad it was helpful!
great tutorial
Thank you! Cheers! Keep sharing and supporting.
Everything was smooth but there were no eddy current formation in my case .During visualization I could not spot one.Can you kindly tell what should I do ?
you are the best
Thanks a lot. I am glad you like the videos. Keep sharing and supporting.
Thanks , this video is very nice .
So nice of you.
very nicely explained
Thanks for liking. Keep supporting.
Thnx a lot buddy ....
Happy to help :)
Perfect 👍🏻👌🏻
Thanks 😊
Did you buy an ansys license for private use? I would like to give it a go, but not sure how to get Ansys. By the I follow your group on facebook as well, and will be purchaisng some of your courses soon. Good work.
I have few doubts.. Please help me !
How can I determine the Characteristic Length of a car with its windows open for external CFD analysis in order to determine the drag force ? Also, what y+ value would you recommend in that case if k-w SST turbulent model is used ?
Hello. Sorry for the late reply.
The characteristic length of the car will be same with the windows open. It will be the total length of the car. I am not sure about the y+ value for your case but you can keep it below or equal to 1 or keep it between 30 and 300. Hope that helps.
👍👍
Thanks!
You are most welcome. Be sure to share my videos with your friends from CFD domain.

Thanks for subbing! Stay connected.
how can i take the crosswind to study stability? where i write the crosswind value as an input
Eu te amo com todo o meu coração ❤️
Eu também te amo❤
hai i want to ask, i have done the geometry and when i want to generate mesh, it said that failed mesh, what should i do? thank u
Hello. Make sure that the boolean subtract operation has been performed correctly. Then you can reduce your element size slowly until the mesh gets successfully generated. Keep sharing and supporting.
make sure that the domain is far greater than the model or vehicle and don't forget to keep outlet side greater from others as explained in the video
why didn't you use inflation ?
do more videos sir
Thank you so much for appreciating my work. More videos are on the way. Feel free to drop your suggestions here.
Hey can you tell me why car is placed at the center of the enclosure
Hello. Ideally the wake region behind the car should be greater than the entry region so that we can accurately capture the flow behind the car.
But in this tutorial for simplification purposes the car is placed at the center of the enclosure.
on the solution part it dont be going down the arrows and i dont know why i have preeated everything thrice
hi bro! how to calculate the drag coefficient?
Hello. You can calculate drag coefficient in FLUENT by going in reports > forces > select the drag direction vectors and press compute. In the right side corner of console you will get value of drag coefficient.
My imported body won't line up in the middle of the coordinate system. Any help with that please? When I apply the symmetry it won't cut through the middle of the body. Please
Hello. You may need to move your geometry with move option or assembly > align option in spaceclaim.
by perform this simulation how can i calculate the drag and lift coefficient values. response quickly.
Hello. When you print the lift and drag forces you can get the total lift and drag coefficient values in the right side corner of the console window.
Hello Brother did you get the values of those coefficients ? If yes share them ASAP
@@cfdbabaopenfoamansyscfd2972 Please Share the values in a Hurry
trying to analyze f1 car but it is showing too many cells when it gets imported to fluent, i have student license so what can i do to reduce the cell count
Bro try to decrease the element size in the mesh. But you are saying that you are trying to analyse an F1 car. In that case the mesh should be fine so install a cracked version 😊
Error showing while updating the mesh
But iam. Doing analysis of Tesla model s and it has 3000 parts
Pls give solution
Hello. You can send me your CAD model at cfdbaba@gmail.com and I can have a look at it.
@@cfdbabaopenfoamansyscfd2972 ok
not able to extract car model😓😢
did you find a solution?
@@rishitgupta3644 yes
