Ch.18 How to Use Matlab's PDEPE Solver

[@banker007]

thank you sir for your work, its still helping people in 2020

[@HarinduJayarathne]

Precise, simple, fast, easy to understand!

[@michaelmccreary667]

Absolutely phenomenal video. Don't forget to absolutely smash that like button boys!!!!!! I'm going to get the URL tattooed to my face.

[@farhansiddiqui6685]

Sir,very informative video.Where can I find the script for it.

[@simoneferrari7316]

Hi, congratulations for the video very useful and clear. I have a question to ask. In an equation like this:
ρ (∂u/∂t) = D(∂u^2)/(∂x)^2 -u (∂u/∂x) - μρgsinθ.
In Matlab notation (function [c,f,s] = pdefun(x,t,u,DuDx)) , where I put the term μρgsinθ? I have written c = ρ; f = D; s = -u; but I do not know how and where to insert μρgsinθ

[@mdmasumbillah4590]

thanks for your nice work. I have a question. What if C contain T. then how to write it?

[@synerg1x]

Isn't there an error at 18:37? In " pr =h/k * (T-Tinf); " shouldn't "T" be "ur" ?

[@yonidanzig8375]

You are right... Buy why is that?

[@JamMastaJew]

At 13:53 you say for systems of PDEs to go to your website. Could you please post a link to your website? Really really helpful video by the way! Thanks!

[@omarshafi9426]

Hi, why is m = 2 ; how does this make it the geometry? Why isn't it Pi*r*2 for example... What is the unit of 2?

[@andiausliezen]

Great video thx you.
Which parameters do you use for
h (heat transfer coefficient), ... air?
k (thermal diffusivity?), ... also air?
alpa (thermal conductivity) ... maybe water?
Thx you

[@camphopeasu]

No worries! By "the website" I was referring to Matlab's website. The link to their PDEPE documentation is in the description.

[@anirudhmehta4300]

Hey thanks for the very informative video . I tried to run the same kind of code but I am not getting a correct temperature profile.? could you please provide the script for this code.?

[@sanjaykumaryadav3186]

thanks a lot man u have described in very easy way

[@sepidehmajd593]

wonderful thanks

Great explanation!! very useful!! thank you

[@vishwasn5424]

Thank you for informative videos

[@CarbonDusk]

Many thanks for the video.
BTW, do you know what numerical method the "pdepe" uses?

[@panchalchirag22]

Thanks
But it shows some error at DUDX

[@jacobanderson10]

Thanks for sharing this. How do you write infinity in matlab?

[@PrafulPPai]

You just replace T_infinity with its value / variable containing its value.

[@jamesranawadia]

Thank you!!

[@pallavisapkale5445]

How to use c f s for reaction term?

[@wildedibleplantsofthemedit8676]

i love you man

[@juansebastianfajardocamarg1291]

Thanks a lot!!! easy, practical, simple! :D

[@lferor1]

??? Input argument "DuDx" is undefined.
thanks in advance

[@brendenbazzani81]

Thank you🙏🙏🙏

[@yaseenal-wesabi5964]

Dear sir, I followed exactly what you wrote, but it seems that it does not work. could you please share the complete code here.
Thanks

[@pallavisapkale5445]

same here, it did not work

[@sheesh1706]

@@pallavisapkale5445 because its wrong. xl,xr,ul,ul are firstly unused and variables h,k,t,tinf are not in the input arguments of function pdebc

[@LennLala]

if i enter everything just like you do i still get a lot of errors. Am i doin something wrong?

[@saddamhussainsoomro2810]

excellent

[@mohamedkarali5631]

Thanks alot

[@hojjatborhany]

your code doesn't work!

[@pawzet4610]

pde fun hehe

[@cristianbrunchi4346]

This is all nice and dandy; but unless you want to learn matlab in elementary school, not very helpful; how about a system of pde's? How about a system of pde's of which some are function of time and space and some just of time? Now that would help people!
Providing an example more simple than the one given by mathworks isn't helping unless you use matlab, like you say, for fun.

[@wildedibleplantsofthemedit8676]

make a video urself!

[@larslarson1810]

haha wtf are you talking about? get off youtube if you have problems like that.
