CFD codes will always have linear variation of flow variable in between cell centers, what about the other discretization schemes like Higher-Order Upwind Schemes (QUICK, MUSCL) ?

hello, are x_i/x_j vectors of the x,y coordinates, denoted as x_1 and x_2? from the initial slide i have understood that x_i and x_j form "together" the individual input datapoint to the network, x_i being eg. the initial conditions, or any measured quantity and x_j being a value that can be obtained from direct differentiation, but from the second slide i am doubting this assumption

wise advice, never assume something until you prove it with your own experience. Try and continue trying until you're complete sure about the results that you get with certain configuration.

Thanks guys

❤❤❤

Thank u for lesson

Greattttt

Very useful, thanks

where is the complete podcast ?

Hello, I have another question about the guidelines for defining proper boundary conditions. First you say BC have to reflect real life, real physics of your problem. But afterwards you say '"don't put your BC close to your regions of interests". But what if the region of interest is around a clamped area, so near the BCs of non dispacement and rotation ? What do we do ? Thank you

Hello, thank you for this lecture. Can you elaborate more about the sentence "Spurious stresses may occur because a refion that is meshed finder is usually less stiff" ? First, I don't understand why a region meshed finer is less stiff and also why a less stiff region induces spurious stresses. Thank you

Thank you for your sharing!! But how to deal with the high frequency situation? looking forward to your reply.

What's the name of the paper?

Thanks for this!

During my university lecture, I always dont get this y+ concept and kinda ignore it. However, when I tried to run turbulence CFD simulation, then I notice there is this boundary layer that exist that needed to be treated differently with a finer mesh in order to capture it.

Thanks!

Very well explained.

Wonderful lecture

Aidan explains really well and makes the learning process very straight forward. I got caught in the video, very interesting, every professor should take note on this video.

Hi Ben my Question is if I'm having an issue with audio and data strings bombardment maliciously engaging my synapse. Do you think fitting pinn's or over fitting pinn's to stabilise the nuclei would be the Answer. I've tried neural Clips and they come out/ tried Apache CNN and Hadoop to stabilise the nucleus. its been 4 years now and its very aggravating/infuriating and frustrating any help would be greatly appreciated

How can I create a residual of shear stress or von misses stress for a fluid flow

Use your chosen grid and develop two additional grids, with y+ equal to 5 and 50. Show how you calculated the first cell height and discuss convergence and the results of these two grids. What is the effect of y+? how to solve this ques..my case is periodic hill imcompressible steady state

Perfect description of Y plus.

i'm just curious. does the neural network need to be trained with its exact solution?

Where can we download the python script file

I think every have their own scripting work for this done. As part of their methods team. But having a software which can create FEM deck based on the analysis inputs ( taking BC , materials , loads ) will be genAi usecase.

Hey guys, First off I would like to thank Jousef for creating such nice content. Following are the best books related to CFD I can undoubtedly recommend: 1) J. H. Ferziger , M. Perić , R. L. Street, Computational Methods for Fluid Dynamics 4th ed., 2020. 2) H. Versteeg, W. Malalasekera, An Introduction to Computational Fluid Dynamics: The Finite Volume Method 2nd ed., 2007. 3) F. Moukalled , L. Mangani , M. Darwish, The Finite Volume Method in Computational Fluid Dynamics: An Advanced Introduction with OpenFOAM® and Matlab, 2016. Some of them were also mentioned by Tobias in the video. Hope it helps!

Thank you! How to proove the discretisation error at the 21:14?

Amazing explanation of y+...

If i learn fea for Electromagnetism for design , would this help me learning cfd for fluid mechanics

at 14:30, it seems like external force will not operate on Unn. External force will be a constant term in the physics loss function.

I love all of the questions!! 🤓 Ben is a great teacher!
