Hello what are the software’s required for this work all software which you have used in this video please tell me
how and where can i get the tyre geometry
can you tell me the name and mode of your system?
Is there a way to have fluent output the air exchange effectiveness value rather than having to use a separate calculator program? I would like to make a contour plot that shows air exchange effectiveness. Right now I am only able to make a contour plot that shows age of air.
please share the wing design
how to design the wing of this aircraft.
permission, where is the place to download the geometry
link download geometry is expired
I have a question. When you click "Sizing" and then under "Definition" i don't have "Body of Infuence". What should i do?
Very well benefit of this , thx sir 👍🏻
sir can you please do airfoil with flap :)
In this how to find the cd and cl of the tyre..?
Salam i didnt watch tis video but you can MAKE group and find cf and cl of tyres
Why did you include the UDS, after the velocity at the outlet, converged? Does it not work if you include the UDS from the start? Thank you
Promo_SM 😣
I find the cd values to low with slang angle 80 degree I changed just chamber part in design modeler, I have used same mesh but cd is coming 0.28 it is too low with this slant angle how ı can change?
Waiting for the next part
amazing!!! Thank you so much for sharing this!!!!!!!!!
Hi thanks for this.
Thx for sharing sir 🤝🏻
Great job
Hi Sir, how can I set an other AoA? We have only farfield module. Is it possible to set an X and Y velocity value?
The drag coefficient is too low?
how did you change
@@dogjaguar6frontal area should be 0.056 in ansys reference values… Because we halved the ahmed’s body
Thanks for this tutorial. I didn't understand one part. How did you manage to set x axis starting from 0 to 1 or default setting is like this?
mine gets stuck on "attaching to assembly" ?
In our work, the density is constant. So the source of mean air age will be constant everywhere. Kindly explain..
this was super helpful thank you!!
Great tutorial! One thing I don't understand is why we used a pressure solver rather than a density solver in compressible flow
Can I get 4 instead of 36 in setup? does this cause a problem? I can't run it because I'm a student licensed.
no
Inflation and face mesh are closing each other, what kind of way should be followed to solve this? I want to give inflation to my airfoil, for this I found my first layer thickness value, but the inflation is not given on top of the operations you have done, what is the reason? I am getting invalid method error.
How did you calculate the value of area?? If my cylinder is of D diameter what should be the area in D???

Hello, sir.. This is my final year project, thanks for the video as it has helped me a lot, I am facing an issue in setup, it is showing *divergence detected in amg solver... *, Can you please suggest how to get rid of the error
The first layer height in your video is 0.4mm, but it should be 0.04mm or less if you want the y+ value to be around 30,right?
After building this, is it possible to do a cavitation analysis of it
hi everyone, who can make rans and urans simulation of Ahmed body with discrete adjoint optimization?
Next part
Where is IFSTREAM?
The drag coefficient should be around 1.3 for Re= 100
Excellent tutorial, one of the greatest actually.
Kindly tell what you did between 10 35 minutes and 10 45 minutes?
How long do you run the simulation?
Soooo much click click to analyze a single airfoil !!! at one angle of attack !! .. NOPE

what if uref is changing over time in a transient simulation? how can we do this in the udf? pls any advice
If Uref is changing over time, you will need to create a function that takes “time” as input argument and return the value of Uref. You can refer to the manual here: www.afs.enea.it/project/neptunius/docs/fluent/html/udf/node243.htm

says failed to process a boi, boi either too thin or open? can you help me with this
Plz bring more lectures
Sir, how can i contact you?

There is considerable error in the cd value
did you find out how to fix this?
@@AdamButt04 did it long back. It is all about meshing
@@nidhinkakkanattu2178thanks for replying, I’ll try look at the meshing today and fix it.
