Dear Jousef, can you please estimate how much do you safe when you use simulation compared to a prototype for example in the Automotive industry? Many say the estimations are very good but you still need a prodotype. Can you have less volumes of prototypes then or do you safe a complete phase of hardware? How much is a computing hour or how much does such software cost? I read you need 278.000 hours in simulation for example.
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.
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.
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
Love that you commented on these two topics. I promised an OpenFOAM course some time ago, will work on that in the mid of the year and how to manage CFD projects will hopefully also be started soon :) Keeping you posted. Feel free to follow me on my socials to keep up-to-date!
Thanks mate! Sounds very interesting - any special resources you recommend? I can google of course but maybe you can show me some resources that you personally like! Thanks in advance 🙂
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!
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.
Awesome video. I'm a big fan of these, as well as the podcast. Just a comment... FEM is totally relevant in CFD, and I would even argue that it is now the standard. Many people tend to create a false dichotomy between CFD and FEM, which doesn't really make sense. FVM is actually a special case of the FEM, in particular it is an FEM with cell-constant test functions. This is also true for FDM, where test functions are Dirac deltas. Anyway, love the channel!

Great Intro to CFD. I have to perform an individual project, the subject is CFD of behaveoir of CO2 in a fractured pipeline. Jousef do you have any experience in that topic?, if so, can we chat pls?
Thanks Mark! Yes indeed, that’s actually a bug of Premiere Pro when using the denoiser, it’s so annoying. In my new Matlab video that I just released it should be better. I found a workaround to filter the annoying frequencies out. Please give me some feedback if you like it that way :)
Hey, deine videos haben absolute top Qualität, gab direkt ein like! Ich bin eigentlich aus einem anderen Gebiet hier und verstehe ein paar Zusammenhänge zwischen verschiedenen Begriffen noch nicht, kannst du mir vielleicht weiterhelfen? Stimmt es, dass FEM eine Methode für CFD ist? Mich hat hier nur die Tabelle am Ende mit den Boundary Conditions etwas verwirrt, weil CFD und FEM ihre eigenen Spalten haben. Und weißt du vielleicht wo man die Methoden Lattice Boltzmann, Galerkin, Inverse Boundary und Arbitrary Lagrangian Eulerian einordnen kann und vor allem in welchem Schritt von CFD/FEM diese vorkommen? Sorry für den langen Comment, eine kurze Antwort wäre mehr als genug :D
Hey! Man kann den Ansatz der FEM auch für CFD Probleme verwenden aber das sind erstmal von Grund auf verschiedene Gebiete die aber auf ähnlichen Ideen beruhen und zwar bspw. der Diskretisierung einer Domäne in kleine Teile, über diese Elemente werden dann Annahmen getroffen und geschaut ab wann sich eventuell eine Zustandsgröße wie der Druck oder die Spannung nicht ändert? Tut sie das nicht? Ok dann gibts weitere Iterationen die es durchzuführen gibt was uns zum Gebiet der Konvergenzstudien bringt. Galerkin Ansätze oder den Ansatz findet man in beiden Gebieten, findet man durch be schnelle Google Suche heraus. Zu Lattice Boltzmann muss ich sowieso mal ein Video machen :D Hoffe ich konnte dir in irgendeiner Form weiterhelfen ;)
hello Jousef, can you suggest where can I find video lectures on turbulence modelling? Are there any video lectures on understanding turbulence modelling? can someone please help !
Thanks for asking and being so inquisitive! 😃 I thought about either uploading one on matlab using the ode45 solver or another beginner’s guide about the lattice-Boltzmann method. Depending on my workload it should appear at the end of the weekend, hopefully.. :)
By using transport theory of species through fluids. In that - i) Mass conservation equation as per your dimensions. ii) Momentum conservation equation (To study its velocity & streamline patterns, effects of pressure differences, buoyancy forces if required, etc.) iii) Species transport equation which strongly coupled with mass conservation equation. iv) Energy equation - This is optional if your requirements in design involves heat transfer effects like natural convection of air particles or if external source of energy used like fans or blowers to move forcefully the air in room for maintaining its quality. v) Physics of saturated or unsaturated fluids & its thermodynamics aspects should be the primary requirement that how governing equations as mentioned above are involved in actual process of simulation. vi) Boundary conditions like temperature, pressure or velocities, contaminant or impurity concentration variations should be specified in the problem statement. vii) Study basic meshing techniques like hard or soft, fine or coarse, its geometries like tetrahedral or hexagonal, etc. viii)Choose steady state or transient solver with proper time steps & convergence criteria as per availability in software. If you wants final air quality status throughout the room then you can perform the steady state analysis. If you wants the status of complete process under some time frame then choose transient solver. ix) Can choose proper flow models like laminar or turbulent. Laminar models are preferred for very low air velocity flows otherwise, choose turbulent. In turbulent, there are many commercially available models like k-epsilon, k-omega, omega-SST, Algebraic y+, LES, or any other, etc. Read some of the research papers on simulation of air quality in buildings or a room. This will give you more insights.
Hi I have a project on CFD on "Unsteady flow over an accelerating flat plate- MacCormack's Approach" Where I have to solve the convection-diddusion equation by MaCormack's Explicit scheme in MATLAB...Can u please help?
I could do a tutorial on the convection-diffusion equation which was planned anyway but not for this particular application. The goal would be to interpret the so called Péclet number for stability purposes. Not sure if that helps.
@@JousefM ok sir...But can you do a video on the above scheme and it's implementation on MATLAB code for this equation with appropriate initial and boundary conditions...?? Plzzzz
@@shuvranilsanyal1018 I have heard about that scheme but never implemented it. Can see what's possible but have other things that are high priority at the moment. On my to-do list in any case!

Many time for the new person to the cfd world he wants to know much more on where is it being used, what has been done with it. i dont know. maybe its a bad recomendation. (im talking like at least 100 examples or something a bit extensive of examples and "real" aplications)*
hi Jousef, thanks for all the videos u put..i am new to the vast field of CFD, i can understand all the CFD schemes and theory stuff, but i have zero coding skills.. and so i am feeling stuck... should i take a basic programming course or just learn matlab/python for numerical methods or CFD problems?? plz appreciate ur suggestions
There’s some good ones on RUclips using matlab or Python. You can also use the book „Modern Fortran“ if you like hardcore stuff from Milan Curcic. Highly recommend this one!
@@DylanCVlogTV Was not sure if it was joke though ;-) But to answer your question, they definitely do CFD verification and validation but the problem with the 737 was a complete different one if I remember correctly (sensor/software issue!?) - so CFD would not have helped here.
Going on slowly in the background. I though I’d rather have a „documentary“ kind of intro to turbulence and also cover beginner questions than to have a huge series. A turbulence course might come in the future with coding examples - high quality takes time my friend. Just know I’m working behind the scenes 🙂

Danke 😅 find mein Englisch super normal, angefangen hat alles mit zocken wie bspw Dota oder Counter Strike in Clans, sprich man war gezwungen englisch zu sprechen. Ich glaub für jeden Skill ist es wichtig, dass man sich dazu bereiterklärt doof auszusehen und man dadurch dann sukzessive besser wird :) Grüße aus Karlsruhe 🙂
@@JousefM danke für die Antwort ✌️☺️. Ja das Problem mit dem eigenen Ego aus dem weg räumen, des hab ich jetzt auch schon ein paar mal gehört/gelesen 😬 👍. Na dann weiter so, du machst gute Videos und deine Reichweite kann sich sehen lassen 😉 liebe Grüße.
Thanks und einfach dran bleiben. An der Reichweite ist definitiv noch was zu machen - müssen wieder mehr theoretische Videos kommen 😏
@@JousefM RUclips ist ein Schnellball einfach weiter rollen lassen 😉
