[druznia]

You are the one! I dont understand other indian guys talking but your pronunciation is perfect! Im glad to say that thank you and make more videos for us.

[deep_diaries]

Very Helpful Video. Clear & Concise.Thank u Sir.

Is there a video on solving Parabolic PDEs using Implicit Method?

[rvignesh]

Do you have a video for finite difference approximation of 2 D heat equation for a disc in polar coordinates? Especially about handling the 1/r at the origin?

[Hobbit]

Im just at calculus 1 in school but i find this very interesting. I tried to model the temperature distribution in a concrete wall in a house.  
So basically i wanted the inside temperature to decrease exponentially from 25 to 15 degrees in 1h and then to be fixed at 15 degrees after that time. The outside temperature is 2 degrees.  
Can i then have a boundary condition like u(0, t)=2+(25-2)*e^-st (newtons law of cooling) for t<=3600s and then u(0, t)=15 for t>3600s.

( u(L, t)=2 for the other boundary)

how to implement derivate dT/dx =0 condition in fdm method

[dannykusuma]

very helpful and easy to understand, please make another video of numerical method

[The_Aawara_pahadi]

did the problem statement will always give us the initial value which we will take for the interior points

[sehrworld]

What are other examples of parabolic pdes except heat equation?

[mohamadhidayat]

why the value of Lamda is always same with the change of t?

[karthiknair]

Why you have taken the value of j = 0 for t=3s when it should be j=1 bcoz
t=0s, j=0
t=3s, j=1
t=6s, j=2
t=9s, j=3

where did u get the Temperature value for each interior nodes? i dont understand T, T

[makervishal]

really good explanation thank you sir.
