Nice technique! Does your back hurt with your posture while you're playing for a long period time? Also, a really like your lectures! Have a good day!

Gracias por subir el curso profesor Saad.

Please share the code sir

Incredible hands-on explanation of the fundamentals of FVM. Thank you for the video.

Amazing the perspective that mathematics can provide. Excellent work!

this is fantastic. i really appreciate the lecture!

This video gets a big BOOM

Me encanta tu curso gracias por subirlo.

Professor Saad, you may be comforted to know that I laughed at 7:24 while sitting here in Raleigh.

Thanks Prof Saad, is it possible to share this code?

Couldn't you just show the presentation? We don't need to see the class participants.

When I tried to run it, It says "list index out of range"

What a wonderful lecture. Well done!

Professor, Thank you for such an amazing lecture.This was such a huge relief to understand what is going on when we solve hyperbolic equations with higher order linear schemes. I was wondering where I can find rest of the lectures. I appreciate the positive response.

yes it was very helpfull. But I want to ask how can I make my proggram able to read greek latters (for examle a pdf file)?

Can someone explain why the bottom equation at 28:00 has l_1 d/a at the right hand side? I do not see where this comes from if this equation follows from l_1 dv/dt + l_2 dw/dt

Is the laplacian wrong here?

your video helped me a lot . Iam in a confusion for indexing for u,v,p. and boundary condition , the way you arranged staggered grid reduce my effort to compute boundary cell values . thank you a lot sir.

Thanks for your efforts. I have been following you from Congo-Brazzaville.

ruclips.net/video/SHoMEROQ9_E/видео.htmlsi=iS1ZvDZZqPHkVjbD Here a video doing the math and it shows the speed of the implosion 4 milseconds(816mph)...1 milsecond would insanely fast at (3239mph)

Dear professor Saad, Very interesting talk, thank you very much. I would have some questions if you don't mind, sorry if it's a bit messy: At 2:50 you are talking about thermoacoustic interactions right? I'm writing my PhD on this topic and I'm still unsure what would be the best approach to tackle such simulations. For example, I have simulated a laminar flame that is perturbed by a variation of the inlet velocity and I have studied how the heat release is impacted, I think for this configuration, the "low-Mach" assumption is fine. Now if I want to consider acoustic waves interacting with this flame and see the impact of those wave on the heat release, can we still use a "low-Mach"/pressure-based solver? So far I have only used pressure-based algorithms (derived form of the SIMPLE-PISO algorithms) for reacting flows, but it seems that a part of the research community dealing with compressible flow is critical toward such methods. The space and time discretization schemes employed in pressure-based algorithms tend to be very dissipative (low order implicit time stepping, upwind schemes ...) and we could loose some information. Also when we are dealing with reacting flows we still need a small time step (~1e-6 to 1e-8 s) when taking the fast chemical reactions into account, in those case the iterative process to solve the linear system used in pressure-based algorithm is not so efficient anymore and the speed-up in calculation time that you show at 13:47 won't be that great. Finally as you show at 16:00, pressure-based algorithm don't scale that good in comparison to density-based. I would really appreciate to have your feedback on this, and thanks again for all your work on RUclips to make CFD more accessible.

would be real great if you can share the staggered grid map with us ? one of the fans, here

how to solve this problem over time, with the implicit scheme or CN scheme ?

Can't thank you enough for the content that you create 😊 Keep the good work up!

This lecture is pure gold. Thanks for all your effort.

Please give us name of this course, can't find lecture 1 of this

I learned a lot thank you!

didn't find the lecture in the 2024 series, came here , splendid lecture , thanks to professor Saad and Dr Kamila

bro that was great

Are you doing FDM or FVM? If FVM, how is it different from FDM?

wonderful course videos, thanks so much!!

Dear Sir, Very Nice. Please your email address. Thanks.

Very nice explanation professor, thanks a lot

Hello Dear Professor Saad, it's missing lectures 17, 18.1 and 8.2...

I really like the classes

Love the lectures, thanks! One question: what was the definition of `uexact` in the code you showed about errors at 20:00?

Thank you very much for publishing your classes Professor Saad, they have really helped me a lot !!

fantastic lecture! This is a really good way to teach these courses. I remember we had an advanced numerical methods course starting at 6 p.m.! two times a week, and the professor was writing formulas and proofs on the board almost all the time, no coding, no interesting examples. I was virtually asleep :). I really appreciate how you step by step build the idea and explain why's, not just how's. It makes me more interested to the point that I want to learn more about the topic and that matters a lot IMHO. Thank you

Still have some microphone problems ... sounds like a loose wire or maybe a low battery in a wireless mic that can't track audio peaks.

Brilliant, as usual.

I greatly appreciate you sharing your lectures with us Sir

sorry you forget lecture 9 video in the Saad s' series?

buenisimo, primer comentario,,,

Could you please share the problem sets?

Why are you swapping the indexing of the u velocity terms when coding the diffusion solution? The solution you have derived in the presentation at 52:30 in the lecture slide is U_i+1,j - 2*Ui,j + U_i-1,j. What you type in your code at 52:40 is U_i-1,j - 2*Ui,j + U_i+1,j.

thanks for your sharing! it is an excellent lecture. Will you introduce knowlege about level set in the future? or could you please recommend some books about it? I think it is an important part when people want to use projection method.

Thank you sir!

could you please upload HomeWorks professor Saad

Nice dear sir.
