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!
well done explaination. thanks. please keep posting more.
Extremely helpful, thank you
A bunchof flowers to my great proffessor 🌸🌸🌸🌷🌷🌷tnx a million for sharing this part with us . It really helped me
thanks man for the tutorials. Please keep posting
Extremely helpful! Thank you so much :)
Could you please do a video on flow over an airfoil and boundary layer separation...
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!
thanks alot its really useful tutorial. its my first time of using fluent and i found the video very clear in steps and every thing
+mustafa sabah thanks!
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?
Thank you for the CFD tutorial. It was very informative and easy to follow.

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 you very much. This was extremely helpful. I would love some advice on how to create a 3D drawing, and apply the same principles.
Thank you DrDalyO! God bless you
after 8 years still the best!
Sensible Teaching ... Good bless you and your kids!!!!!!!!!!
Thank you very much. Your tutorial is very helpful for me
can we rotate the cylinder & graph of coeff. of lift vs spin ratio of cylinder
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
thank u so much, it was really a perfect tutorial!
Thank you so much ! This really helps
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
just loved the tutorial.
When I go to mesh > sizing , I can't find "Max size" for some reason
I also noticed that under sizing, in ny screen it says "Use Adaptive Sizing" and next to it it says "No" and not "On: Curviture"
Thanks. This is a great video. Wait for your next videos
Thanks for sharing, can you do a video for 3D wing with "Assembly" with various AoA? Please
Really it's nice . You explained clearly .Thanks
Appreciate your effort man
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!
can you please do the same tutorial but this time include springs for oscillating the cylinder in X,Y direction!.
Thankyou for the tutorial, was so helpful in my project
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.
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?
very nicely presented. Although working with realistic values of density and viscosity would have been much more better. Thanks for the good work.

Thanks a lot for the great work. Could you please do flow over articulated beams? Thanks
Excellent work..!!!
Thanks... its really helpful
your teaching is fantastic
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?
You helped me a lot bro, thank you
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.
Wonderful video... it was very helpful... You have explained everything very nicely... thanks very much
Awesome video! Thank you!
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 a lot... I can finally generate the turbulence behavior... =)
Thank you Sir, It was really helpful.Can you please upload a video on the use of "wall y+" technique
why do you select "y axis" to calculate drag coefficient?
The video has been very helpful. Thank you!
+Taiquan Liu thanks!
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.
+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.
Very nice and clear tutorial!! Thank you, Sir!
Thank you!
Straight as an Arrow!!
Keep up the good work

It was awesome! I did it! thank you!!!!!!!
you r dominant on explaining and tutoring . good job . thanks
+AMINATION TV Thanks!
Very good tutorial. Thanks a lot.
Great explanation, where do you keep the rest of the videos please, I would like to learn more. Thanks
well done and clear, thumb up
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.
best tutorial on youtube. Thank you very much
Thank you!
Thanks a lot, I hope you do more fluent videos including 3D ones
very helpful video tutorial. thank you.... thank you
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?
thank you , that was helpful , would be nice if you put more videos
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.
This is the greatest video of all time
Thanks so much!!
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
ı just want to ask for calculating the Cp (pressure coefficient) do we need any inputs in the reference value part.
muchas gracias, fue un excelente vídeo, sos un maestro !!
+Rodrigo Alvarez gracias!
Hey, great video, could you please make a video on how to simulate and calculate lift and drag of an airfoil. Would much appreciate
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.
Extraordinary usefull, thanks a lot!
Hai, this video was quite helpful. I wanted to know one more thing. Can we specify the reynolds number instead of giving as turbulent or steady flow ?
Hi, can you please give a tutorial on rotating oscillating cylinder (clockwise and anti-clockwise) about its axis.
Absolutely well explained
Thank you!!
Great video, learn so much. Is there any way to transfer the mesh in the OpenFoam? Really appreciate the help.
Still irradiating! Thanks
Do you have any video for the hydrodynamic response of vertical cylinder i.e. using Morison equation.
Great video! Thanks a lot, helped so much!
Thank you for this wonderful video sir. I am a beginner in this field. I am having a doubt. Is there any way to observe the stress profile on the cylinder body ?
One of great tutorial i have ever seen. Thanks. Do you have tutorial for 3d case?
Thank you for this awesome tutorial. Very well presented.
can we find any other tutorials from you about fluid flow over ordinary shapes and also porous medium on youtube? Thanks
Parry Pal I do not have any other videos yet, do you have a particular shape in mind? i could maybe make a video on it.
DrDalyO The simplest one would be a rectangle of half solid and half porous medium. This can be the start. Simulation of the following paper is also a good practice in order to compare the results:
C. Chan, E. and F.-S. Lien (2005). "Permeability Effects of Turbulent Flow Through a Porous Insert in a Backward-Facing-Step Channel." Transport in Porous Media 59(1): 47-71.
Thank you
hey very nice video and good explanation as well. but one question left, i'm not an expert with fluid techniques but i know that simulation programs are made for measuring parameters.. So my question is what is the target of this work? I mean which parameter could u investigate with this simulation?
I'm trying to recreate similar meshing options but for a 3D model. However, when I apply the edge sizing and inflation options, it doesn't generate the uniform mesh that you see around the cylinder at 5:10. I've manage to recreate the mesh on a 2D model with ease but am only having complications with the 3D model. Any advice?
Thank you!
great job
That's a really nice video, learned a lot. Thanks.
Marco Antonio Thank you!
Is it possible to plot the variation of vibrational amplitude with different velocities. Can the change in velocities be implemented using the expressions in velocity input? Also can we calculate the amplitude using monitors? Thanks!
hi, this is very informative.. can you make a tutorial for a cylinder in 2 DOF , x and y direction in 2d for FLUENT or any kind of help would be appreciated
thank you so much .
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 ?
How do we get the options for plotting lift and drag through monitors in the newer version?
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?
Hello,
I thank you for your generosity.
I need help with my thesis project. I can not have results. Can someone enlighten me?
