Thanks for your nice video. I just want to mention that incompressible flow is not restricted to liquids, gasses can also have incompressible flow, when they flow isothermally (Adiabatic condition) at low velocity.
What a video, i liked how you take every opportunity to show different featured of openFoam using this simple case study, really helpful tutorial. wish you all the best and happy new year
Great tutorial Sir, I really appreciate your effort. you provide almost compete overview of Open-foam. Hope you make video on geometry creation in details. Thank you
This is a really great effort, thank you so much But honestly, It is really advanced for the first trials with Openfoam. I could not run the case, You are describing the details of the post-processing but escaping the details of how to run the case in details.
With original geometry you should have a vortex at each bottom corner, might want to refine the streamline representation. Cavities help validate the convergence is accurate.
@49:14 the colors at the top left and top right seems to have switched because the orientation of the plane is modified (no idea about when it got modified). Clicking on -Z would orient the sliced-plane in correct manner(i.e., less pressure= blue on left top and higher pressure= red on right top)
Hi Cyprien. When you change from the velocity U to the kinematic pressure p, I can't see the results in Paraview, but I am confident I did the tutorial right from the start until 45 minutes. Do you have an idea of what might be wrong with my system/software/simulation? I thank you in advance.
Hello, I am a master’s student trying to simulate the seismic wave behavior in the case of a cavitation layer in the ground at a depth of 2 meters. But I have a problem with inserting and programming the cavity part in the code using the Fortran program.
hello thank you for this tutorial im rtying to run a 3D incompressible laminar case and after six iterations i have a divergence problem can you please help me solve this
hai, i am started to learn the openFOAM, I am following your videos and getting error while giving blockMesh command (Symbol Lockup error : libdecompositionmethods.so : undefined symbol :ZNK4Foam11regI0ObjectENS_.......like this). please solve my problem
hello first of all I would like to thank you for the video it was very useful for me however I have questions about the boundary conditions I can't quite understand how it works for example when we have a hydraustatic pressure or mixed boundary conditions etc how does it work?
hello sir please how i can add a function to the differential equation in openfoam, especially the scale function, *like here : fvm::ddt(T) - (1/(1+dfra(T)*Lat/(CP*eT)))*fvm::laplacian(DT, T) == fvOptions(T) *for the continuous functions I managed to define them by this program in createFields.H volScalarField dfra ( IOobject ( "dfra", runTime.timeName(), mesh ), { 0.5-0*T } ); *but for the scale function i can't difinde (dfra(T)) *the function what i want add it is this: int fraction(int n); using namespace std; double dfra (double a) { double r; if(a>-0.5 && a
@@Feaforall , exactly, just a test case. It's not critics, just thought you'll be curious to know cause you hesitated at this moment. Anyway it's a great tutorial and your brother could change medecin to CFD! Great thanks, especially for the supplementary information about macros using in paraView!
Hello, I don't see any answer on your problem, I have the same one and I was wondering if someone helped you to solve it and what was the solution, thank you !
I wasted so much time asking help for others in my project-assistanship, where as you explained everything in one video. thank you so much 🙏

These videos are so helpful!, Idk what i woud have done with openFOAM without videos like these, tysm ;)
I was almost giving up on OpenFoam but this video saved me! Thank u

Beautiful! So many knowledge packed with time marks in a single video!
So glad this exists. thanks!!
Gorgeous! Thanks for your useful tutorial.
Can't wait for the next tutorial!
nicely explained Sir....you efforts are inspirational
A massive thanks for your work. Everything is just clinical.
Thanks a lot, Cyprien. It was a breeze learning OpenFoam with you. Looking forward to more of your videos...
Thank you very much for wonderful tutorial.
I am new here and great to see much more materials. Great teacher
Thank you very much Sir for your fruitful lesson. Really enjoyed. I hope you will continue this journey.
Thank you for making this tutorial Cyprien. This is great stuff, and having someone to follow is great introduction. Thank you.
Great video explanation! I've watched several of your videos and each of them was useful for me. Thank you a lot!
Thank you for making this tutorial Cyprien. This is great stuff, and having someone to follow is great introduction.
Very helpful video, thank you so much! good pace and well explained!
I can only give one like, so big thank You!
Thank you so much, Cyprien !!!
Thank you, you are very good at explaining these things.
Thank you so much Cyprien! You have made learning CFD so much more fun and understandable
It's a great explanation
I wish I could see this video 2 years ago! Now that I understand Lid-Driven Cavity flow, my PhD time is running out :(.
thank you so much, i can finally understand this
Keep up the good work
This is really good. Thank you

Thank you, Thanks this iI understand fuly the mode of working of the programm

it was modified when cyprien presses +Z @48:12
Thanks. Great video.
Great tutorial. Thanks, like and new suscriber!
Thanks a million!
Seriously man, thanks.
Amazing presentation Cyprien! Request you to create one on cavitation in submerged bodies using interPhaseChangeFoan and Schnerr-Sauer model. Regards
Great video
Thank you for your work
great
Perfect! Thank you!
Thanks a lot sir , very helpful
THANK YOU SO MUCH
Thanks this was useful
Cara, choro d rir até hj! Ahuahaihu
C'est trop bien!
Here se are, with the cavity tutorial
Thank you for the video, i would like to know how to account for gravity in such an example?
Thanks

hi dear sir, could you please make tutorials on using the pure Calculix that deals only with ( CGX & CCX)?
Sorry further in which link can be found? (Stress analysis of a plate with a hole)
hello sir
please
how i can add a function to the differential equation in openfoam, especially the scale function,
*like here :
fvm::ddt(T) - (1/(1+dfra(T)*Lat/(CP*eT)))*fvm::laplacian(DT, T)
==
fvOptions(T)
*for the continuous functions I managed to define them by this program in createFields.H
volScalarField dfra
(
IOobject
(
"dfra",
runTime.timeName(),
mesh
),
{
0.5-0*T
}
);
*but for the scale function i can't difinde (dfra(T))
*the function what i want add it is this:
int fraction(int n);
using namespace std;
double dfra (double a)
{
double r;
if(a>-0.5 && a
Avec la viscosité 0.01 ^(-2) m2s-1 il s'agit probablement du miel. Le rapport des viscosités dynamiques miel/eau est de l'ordre 10^4.
Indeed... this is just a test case!

please recommend some books for basic of fluid dynamics
Can I found this case with Fortran code
BlockMesh did'nt work in my terminal how to resolve it
you have to type blockMesh in the "cavity folder".
when I'm doing high reynolds number case, my cavity gets all red! 1:50:27
and your max is 20, my max is 78!
whenever I reach my last delta T it all gets red, seems like my velocity is way higher than yours
you have very little part of white color inside your cavity, mine is full of white inside blue

When I solve the lid driven cavity problem in ansys fluent then in results part..the screen appears black.. anyone plzz help to resolve this problem.
This is a video about OpenFoam, not Fluent…
