*Important note: At **17:34** there is velocity missing after the density (Rho) - thanks a lot to @Em Jay for noticing!*

I'm just about to start CFD in my last year as an undergrad in mechanical engineering and this has been a very good introduction to the subject.

[vinaynandurdikar]

Really nice video, It talked about the history of CFD. Current cloud based simulation platforms. CFD is solving partial difference equations. partial difference equations are having 2 or more independent variables. like about the divide and conquer thing about discretization. steps in the CFD. Different mesh approach and cell types. Grid types. NS equation which based upon Newton law of motion. Difference between FDM and FVM. Energy cascade in Turbulence. About Reynold number. Models of Turbulence.

Nice video. Enjoyed the history lesson in the beginning. I am enjoying educating people as well with respect to Next-Gen CFD.

[mouhamadmoustafa]

Keep up the hard work 💪 Great explanation!! I will be up with ur CFD FEM series

[HockEnergy]

Great Channel Jousef, keep it up the good work 👍

[carlosmaldonado]

Cfd course of openfoam and derivation of navier stokes equations! And so on 😀😀👍👍

[valmikiramroop]

Somehow I stayed for the entire video. Very stimulating and well researched. Thank you!

[AdrienLegendre]

Very nice video! A computational approach for partial differential equations is using radial basis functions rather than a volume mesh.The solution is represented as a linear combination of functions which are non-zero over a limited domain. The matrix equation then has large non-zero terms near the diagonal so the matrix is likely stable and amenable to algorithms for inversion. No need to determine a volume mesh over all of space other than at boundary. Is there a reason why this is not done for fluid dynamics? I am familiar with the mathematics but new to computational fluid dynamics. Another question, what about Monte Carlo method methods as a solution i.e. a fluid particles with drift and Brownian motion? Thanks.

[abdellamohamed]

very well explained and concise thanks alot

[yuanlisong]

You are super! Making complex simple and clear! Thanks!

[dhanarajsavarynasan]

You can add unified CFD method via FDV theory developed by Prof TJ Chung. It is one advanced topic in CFD as is most powerful tool. Good work

[johnrobinson]

Awesome video. This is a game changer. It seems more like a knuckle ball than a banana ball. A banana ball (soccer) is a curve ball (baseball). Knuckle balls move because air flow around the bal changes from laminar to turbulent unpredictably. Would be cool to see a CFD model show the flow around an Evans punt. All I could find online is flow around a soccer ball punt.

[markkeating]

An important sub topic that needs adding is validation and justifying to what extent you can trust CFD

[mohamednasser]

Thanks that was great job 👍
Keep it up 💪
Waiting for the next
I hope it'll be a weekly tutorial !

[farzanehrasti]

Your teaching method is great. It really helps to see some historical background. Please do a CFD course in openFoam and how to properly manage a CFD project

[bkraj]

Your explanation was excellent. Hatsoff for sharing your knowledge in youtube. Continue your good work bro!!!

[thierrydaoud]

Beautiful video! I will definitely watch the rest of the videos!
My first video watched for this channel was the one with Milan Curcic. I loved this episode, how knowledgeable yet humble he is about his field. I immediately bought his Fortran book (being a Graduate student on my first semester), thank you for the discount code btw!
Looking forward for what's to come!

[nandanseshadri]

I'm definitely up for CFD openFoam course😁
