Finally! Someone who really knows what they're talking about! Thanks a lot, sir! This was exactly what I needed for my project! Very well explained, and with a lot of detail for each step. Please, never stop making ANSYS turorials XD

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

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"

This is the greatest video of all time

This is the first time ever watching such great, clear and helpful tutorial. Many thanks Dr Daly. I learned a lot.

Thank you so much!! I have been an OpenFOAM user and now planning to change to Fluent. Your video became a very good starting point for me. :)

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 alot its really useful tutorial. its my first time of using fluent and i found the video very clear in steps and every thing

after 8 years still the best!

A bunchof flowers to my great proffessor 🌸🌸🌸🌷🌷🌷tnx a million for sharing this part with us . It really helped me

Video is so good that I managed to learn how to use the 2020 version, thank you so much!

Sensible Teaching ... Good bless you and your kids!!!!!!!!!!

Thank you for the CFD tutorial. It was very informative and easy to follow.

very nicely presented. Although working with realistic values of density and viscosity would have been much more better. Thanks for the good work.

Absolutely well explained

I really appreciate this tutorial. Please keep up the good work! Liked and subscribed and looking forward to more awesome stuff.

thanks dude. it was extremely helpful and i learned a lot.

Thank you sir

Fantastic video, it's nice to listen you. You explain things clearfully and precisely. Thank you!

Thank you so much that was very helpful

best tutorial on youtube. Thank you very much

thanks for this tutorial sir.

you r dominant on explaining and tutoring . good job . thanks

Really it's nice . You explained clearly .Thanks

Thanks for video and i wanna suggest you one thing, pleas put a pointer gesture so that the pointer position could be easily detected...

Wonderful video... it was very helpful... You have explained everything very nicely... thanks very much

Helped a lot..... still a tonne of things to learn about Ansys fluent! Thanks, DrDalyO!

Awesome video! Thank you!

thanks man for the tutorials. Please keep posting

Very nice and clear tutorial!! Thank you, Sir!

why do you select "y axis" to calculate drag coefficient?

Very helpful video. I highly appreciate your efforts. keep up the good work

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

Very nicely presented.Good work.

Very good tutorial. Thanks a lot.

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!

Thanks a lot sir for sharing knowledge

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.

your teaching is fantastic

Thanks. This is a great video. Wait for your next videos

Straight as an Arrow!! Keep up the good work

just loved the tutorial.

Extremely helpful! Thank you so much :) Could you please do a video on flow over an airfoil and boundary layer separation...

Hi, can you please give a tutorial on rotating oscillating cylinder (clockwise and anti-clockwise) about its axis.

well done explaination. thanks. please keep posting more.

Thankyou for the tutorial, was so helpful in my project

Very nicely explained......sir can you please show some tutorials on welding of two plates and doing there fluid flow analysis at the weldpool

How come the "wall"s of the domain produce no boundary layer along itself?

can you please do the same tutorial but this time include springs for oscillating the cylinder in X,Y direction!.

thank you , that was helpful , would be nice if you put more videos

love the way you explained all the process involve , but somehow i as student cant relate how the set up will affect the analysis , which i need some explanation in term of simulation so that i could understand better. Thank you for the video

Thank sir Please add from beginner to expert series

thank you so much .

can we rotate the cylinder & graph of coeff. of lift vs spin ratio of cylinder

That's a really nice video, learned a lot. Thanks.

Thanks for sharing, can you do a video for 3D wing with "Assembly" with various AoA? Please

Thanks you very much

Thank you very much. Your tutorial is very helpful for me

The video has been very helpful. Thank you!

thanks so much

Still irradiating! Thanks

Great job sir 👌👌👌👌

How to determine the time step size and number of time step to get maximum accurate result but don't need much time to complete running?

How to implement lift and drag report in monitor? Because it's not there in my monitor option of setup only residual one is there.

How can I make this cylinder rotates? just to detact the effect of the rotation on Von Karman street? thanks

Extremely helpful, thank you

Very nice tutorial. The best on youtube so far. Can I request you to please put a few more fluent examples (FSI kind maybe?), if you find the time. It'll be a big help. Cheers!

thank you very much sir please can you post how to calculate forces and modelling and simulation using ansys fluent on submerged vertically moving circular cylinder in fluid

Thank you very much!! Great video

thank your very much for the video..but I have a problem in the result section...i got only one time step in the list of time selector even though the number of solver step is 207...

muchas gracias, fue un excelente vídeo, sos un maestro !!

Excellent work..!!!

This is extremely difficult to do on the new version haha. Can't follow well enough. Anyone having success with the 2020 R2 academic version? thank you!

I have problem like point exception command while i operated fluent flow command for rotating propeller analysis , please make video to solve my error.

Thanks a lot for the great work. Could you please do flow over articulated beams? Thanks

Great video! Thanks a lot, helped so much!

can you make a tutorial on turbulent flow, with k-epsilon and k-omega models plz asap

well done and clear, thumb up

why is the red region in ur current screen{not the saved animation file} not visible i am having the same problem , when i am starting the animation from 0 timestep , i am not getting the red region

Appreciate your effort man

I am only getting two values in timer means only two simulations by following same procedure....plz help

Hello, i wanna analyze a golf ball. You put the empty cylinder shape in the middle of the domain. How can i make the golf ball shape at the center of the domain?

thank you so much you!re the best teacher

Thats really a gud video,Sir Can u plz describe hw we have to mesh the things ,if a cylinder is placed in a block to anlysis natural convection over the cylinder ,hw really it vary with respect to their boundry conditions

very helpful video tutorial. thank you.... thank you

Thanks for the video....I am getting cd as 0.46 for the same geometry and same velocity? Strange.... What could be the reason?

thanks for this men! solid stuff! If you have time, can you look into doing RT instabilities?

I got the residual and lift plots, but the drag plots are not showing. Any idea?

I like this video, it is helpful. I was wondering that how to simulate a airfoil with different angle of attack in a fixed domain. I basically have the problem that the whole fluid domain is rotated when l wanted to give only the angle of attack to the airfoil only.

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.

Why did you use the Laminar option for the viscosity?

thank u so much, it was really a perfect tutorial!

hi dear , i want to work in fluent for jet breakup, but i dont know ho to develop back pressure in cylinder. same like inside engine cylinder pressure . and the injection by done for miliseconds. plz guid me about it

Hi Dr Dalyo, I am modeling vertical axis wind turbine ( VAWT ), I get confused with the time step size and the number of time steps. I suppose to get my result for two complete revolution of the turbine. I will be grateful if you can advice.

Great explanation, where do you keep the rest of the videos please, I would like to learn more. 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

i tried the same way mentioned here, but meshing near circle , am not getting uniform mesh as yours..instead am getting some wavy mesh ..am using ansys 2023 R1 ..i think something default setting affect the meshing ..any idea any body

Can you seperate the domain to different regions with different mesh? For example behind the cylinder we want finer mesh( for karman shedding) than in the inlet boundary. How can we do that???

Nice work DrDalyO! Please upload a tutorial on a cylinder in 3D domain. Thank you!

when I follow the same steps, I am getting unsurpassed body error at the solve step. I guess this is because of that free area inside the cylinder, any help?
