Finally! Someone goes over it all! The amount of videos I've seen where they don't post the whole derivation or even the equations...

Elvera Keys

thank you sir for making thee videos in detectors

Barton Dam

great explanation, thank you

Probably your most important video in this series

00:05 Example of solving internal heat generation in a 1D slab by hand 01:34 Deriving 1D HT with Internal Heating using FEA 03:11 Solving the problem involves evaluating matrix coefficients and the right hand side 04:41 Understanding derivative values using 1D HT 06:15 Matrix diagonals and off-diagonals have specific coefficients and interactions. 07:53 FEA leads to sparse matrices due to many zero values in functions. 09:33 Calculation of matrix values in FEA for internal heating 11:08 Finite Element Method can achieve exact solution at nodes with piecewise linear polynomials

Unbelievably helpful.

this was great!

thanks!

Thanks for doing this tutorial. I really appreciate it.

Great lectures, thank

Regarding the minimum element size its constraint by the Courant number in dynamic/explicit analysis. I guess this has to be calculated manually? Thanks for the video!

So, basically would it be possibile to get the same accuracy using a lower numerical scheme ( let's say upwind) but using a higher number of nodes?

very useful series, thank you

Hello Sir, Can we Import the Sketchup File in Simscale for Wind flow Analysis

Great Lectures Sir

Only thing missing is you didnt discretize the source terms (grad P etc), but otherwise great. Thanks

Great, very good.

This is actually a very good, comprehensive overview, with just the right amount of math and physical reasoning. Good job, thanks

Thanks for these videos. They are very helpful.

These videos are awesome. I keep coming back to the basics from time to time.

Congratulations for this very well explanation.

Thankyou for helping…i was stuck in this problem…i am in stamdard 11th in india…and preparing for Jee exam

Thankyou sir

thank you so much for these videos!!!!! very very well explained.

Thank you for making this series! This is super helpful!

Nice lecture, thank you

Well explained! How does this compare with the Galerkin method, or is this the Galerkin method?

Very nice 1 hr session on Finite Volume Method. Would be interesting if you have any other videos more detailed on conservation equations and programming also.

You explained it better than Chat GPT 4!! Thank you very much!

A real explanation would describe normal beam splitter, on-axis beamsplitter, and off-axis beamsplitter.

The first part of the integral vanishes only at the boundary right? Becase w(x) will not be zero in the intermediary nodes, even if temperature at boundaries are known. Also, I am not able to mathematically grasp how w(x) = 0 if boundary temperatures are known. They should be 0 even if the boundary temperatures are unkown, cz them being 0 is because of all the tent functions being 0 at the boundary.

great job explaining the weak form! (and the job of the test function in particular)

i so needed to understand it this way. thanks!

Hello , how can we get to the final solution of the partial differential equation

Thanks Joseph

Why Lucent uses BIAS TEE, in some of its EOM, for example model x2623y

What will be the two output modes (a preferably mathematical expression) of a polarizing beam splitter when the vertically polarized state is in one input mode and a horizontally polarized state in another input mode?

Sorry,Sir ,I think you say something wrong,you should write Vx(B) -Vx(A)=(kf-kb)×a

Dude, I love this shit.. Thanks! Jijiji

It helped me to resolve an exercise in Halliday-Resnick's fundamental physics book. Thank you!

Dear Sir, Amazing watching and learning from videos. Was wondering where can i get matlab or C codes for that..its so ahrd coding them sometimes.. Would really appreciate your help . I am a PhD student in Japan trying to develop my own TDTR system. Thank you so much and have a lovely weekend Sir.

So for unpolarized light this is a 50/50-beam-splitter?

Hi Joseph, thanks for your clear and straightforward explanation. Quick question, could also have started off by choosing (T-T_inf) as u*(T-T_inf)? I did that and still arrived at the simpler equation you had, but wasn’t sure if it’s a valid approach. Obtained the same tc and xc as you had. Thanks.
