Video is so good that I managed to learn how to use the 2020 version, thank you so much!
Used the video on version 2024 R1 (as a complete beginner) and still works wonders!
thank u so much, it was really a perfect tutorial!
Very good. A must watch video to learn about so many things like geometry for external flow, meshing, transient solution, create plots, movie and von Karman effect
Thx!
Thank you very much. Your tutorial is very helpful for me
A bunchof flowers to my great proffessor 🌸🌸🌸🌷🌷🌷tnx a million for sharing this part with us . It really helped me
Thank you so much ! This really helps
Extremely helpful! Thank you so much :)
Could you please do a video on flow over an airfoil and boundary layer separation...
Appreciate your effort man
Thanks. This is a great video. Wait for your next videos
Thank you DrDalyO! God bless you
Thank you very much. This was extremely helpful. I would love some advice on how to create a 3D drawing, and apply the same principles.
just loved the tutorial.
Sensible Teaching ... Good bless you and your kids!!!!!!!!!!
Hi there, great video by the way! really helpful! I have one question: How much more refined does the mesh need to be, in order to run the same case but subjected to a higher Reynolds number - Say 10^4. Thank you!
after 8 years still the best!
can we rotate the cylinder & graph of coeff. of lift vs spin ratio of cylinder
Really it's nice . You explained clearly .Thanks
Excellent work..!!!
It was awesome! I did it! thank you!!!!!!!
You helped me a lot bro, thank you
Thanks for the video! Super useful! I just have one question, how do you calculate, let's say, flux of flow rate in one cell of the mesh using the cfd-post over each time-step?
The video has been very helpful. Thank you!
+Taiquan Liu thanks!
Very nice and clear tutorial!! Thank you, Sir!
Thank you!
Thanks... its really helpful
Thankyou for the tutorial, was so helpful in my project
Very good tutorial. Thanks a lot.
Hello dear Dr. Dalyo, thank you very much, if we have a rotating airfoil of a vertical axis wind turbine and we select the airfoil to monitor the lift coefficient and we set the force vector (Y direction =1) as the default settings, will the lift coefficient be accurately calculated when the airfoil changes its position? will the calculated lift coefficient be always perpendicular to the drag? Thanks
That's a really nice video, learned a lot. Thanks.
Marco Antonio Thank you!
Straight as an Arrow!!
Keep up the good work

your teaching is fantastic
Awesome video! Thank you!
Hi Dr Dalyo,
I am working on a 2-way Fluid structure interaction project related to RBC in capillaries.
I have designed a micro-scale shell RBC and a fluid medium which has diameter just above the dia of RBC.
In the transient structural analysis I have defined two fluid surface interfaces:
1. Exterior portion of RBC 2. Interior portion of RBC.
In the Fluent medium I have defined the walls, boundaries of capillary tube and cytoplasm (hollow portion of RBC) which are supposed to interact with with the solid RBC in Transient.
I have assumed that blood runs at x velocity and cytoplasm relatively at 0.97x velocity. Similarly, in transient I have 0.97x velocity, 9.7x displacement to Solid RBC
When I run the analysis by coupling both systems I receive error by doing so. But if I reduce the time step (0.0004) sec for 10 sub-steps ,velocity to 0.0000097x and displacement by 0.000097x solution runs smoothly.
Irrespective of correctness of result, Could yo please tell me why is that if i decrease the velocity, displacement and time steps there is result and why if i consider real time scenario this does not work?
Thanks
well done and clear, thumb up
muchas gracias, fue un excelente vídeo, sos un maestro !!
+Rodrigo Alvarez gracias!
very nicely presented. Although working with realistic values of density and viscosity would have been much more better. Thanks for the good work.

Thanks for sharing, can you do a video for 3D wing with "Assembly" with various AoA? Please
you r dominant on explaining and tutoring . good job . thanks
+AMINATION TV Thanks!
Great video! Thanks a lot, helped so much!
thank you , that was helpful , would be nice if you put more videos
best tutorial on youtube. Thank you very much
Thank you!
Thanks a lot, I hope you do more fluent videos including 3D ones
Very nicely presented.Good work.
thank you!
can you please do the same tutorial but this time include springs for oscillating the cylinder in X,Y direction!.
Thanks a lot for the great work. Could you please do flow over articulated beams? Thanks
very helpful video tutorial. thank you.... thank you
Thank you Sir, It was really helpful.Can you please upload a video on the use of "wall y+" technique
Thank you Dr Dalyo , if I want to place the cylinder in different locations near and far from the wall and simulate it how can I compare the drag and lift force of both geometries, THANK YOU
Thanks for the video. It gives me a nice start to learn fluent.
In my research I need to know odor transport where the source is on the floor. If the odor source is assumed to be an round inlet on surface body emitting the odor, how can I create this inlet?
Thank you!
Extraordinary usefull, thanks a lot!
Thanks a lot... I can finally generate the turbulence behavior... =)
Thanks for the useful tutorial firstly. I have a question about the curve of the drag and lift force. I continue to run simulation by using a time step 0.01s but get a different curve for drag and lift force (between -0.15 and 0.15). could you tell me the time step size you used for the lift and drag force curves you shew in the vadio. Another thing is in the Results part in workbench, you shew a result with about 248 time step and time step size 0.01s.
why do you select "y axis" to calculate drag coefficient?
Hello, thanks for this nice and useful video. In a transient case I want to get pressure data at predefined locations. I have x, y and z coordinates of hundreds of points. How to get pressure data at those locations? Thanks in advance.
This is the greatest video of all time
Thanks so much!!
Nice work DrDalyO! Please upload a tutorial on a cylinder in 3D domain. Thank you!
Thank you for your video, and could you please give me information about the u velocity near the upper and bottom wall being almost the same as the main flow while the boundary conditions are set to wall?
Wonderful video... it was very helpful... You have explained everything very nicely... thanks very much
One of great tutorial i have ever seen. Thanks. Do you have tutorial for 3d case?
Great job sir 👌👌👌👌
Hey, great video, could you please make a video on how to simulate and calculate lift and drag of an airfoil. Would much appreciate
great job
Great explanation, where do you keep the rest of the videos please, I would like to learn more. Thanks
Hi and thanks again for your wonderful video.
What if we want to put a porous cover around this circular cylinder and see how the fluid flow changes?
how we can introduce that porous cover into Ansys?
Thanks.
Hi! I got a different plot when I turned on Autorange for the draft and lift plots and got a similar one to yours when I used the limits in tutorail. Can you explain why there is a variation between the two?
great video, man.
Thanks!
sir.. your video was very informative in the sense of using fluent. I need to know about how that time vs drag and lift coefficient graph are generated after this analysis. In general how to generate any property change vs time graph after a transient analysis being done .
thank you in advance
Very helpful and clear! I am a new user of Ansys Fluent. Can Ansys Fluent be used to simulate Oscillating grid turbulence? I am guessing I can use dynamic mesh and transient analysis? Can I use steady analysis in time? Thank you?
thank you so much for this video I would like to ask is there any way we can see the plot of vortex induced vibrations.
Thank you so much that was very helpful
welcome!
Absolutely well explained
Thank you!!
Hi, can you please give a tutorial on rotating oscillating cylinder (clockwise and anti-clockwise) about its axis.
ı just want to ask for calculating the Cp (pressure coefficient) do we need any inputs in the reference value part.
Hello,
I thank you for your generosity.
I need help with my thesis project. I can not have results. Can someone enlighten me?
Thank you very much!! Great video
Thank you!
Thank you!
+DrDalyO
Also - another stupid question - when I try to run the same thing in 3D, it doesn't seem to work and I can't really seem to figure out why.
Can you perhaps post a little video tutorial about that as well? Thank you.
Hello!
Can you tell how to make an animation of the vorticity and what do to if that variable doesn't show up? pls
appreciate the effort and your videos.
thank you so much .
what is dimension of inlet, outlet, top n bottom
Very nicely explained......sir can you please show some tutorials on welding of two plates and doing there fluid flow analysis at the weldpool
Great video. I am currently working on the flow or vortex induced vibration for a flow past a cylinder. So basically I wanted the cylinder to vibrate in heave motion due to the vortex effects (here the cylinder vibrates due to pressure fluctuations or oscillating lift force). Can anyone help me with this?
How do we get the options for plotting lift and drag through monitors in the newer version?
Great video, learn so much. Is there any way to transfer the mesh in the OpenFoam? Really appreciate the help.
Although I was not able to run the simulation after 0.5s, has some problem with time steps as many options have been changes in ANSYS 2020. Have to say, I learnt a lot.
thanks for the video is really very helpful. my question is about the divergence detected in AMG solver . in fact i'm runing a calculation of lfuid around circular cylinder with different mesh size some folders show me this error when i run the calculation. i don't think that i have a problem with the mesh right ?
Still irradiating! Thanks
Do you have any video for the hydrodynamic response of vertical cylinder i.e. using Morison equation.
