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.
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?
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 t3600s. ( u(L,t)=2 for the other boundary)
Subscript i represents the location and j represents the time node. For example j=0 will be t=initial value of time, j=1 will be initial value of time+delta t. See nm.mathforcollege.com/mws/gen/10pde/mws_gen_pde_txt_parabolic.pdf

Is he from Indian? :D Omg!! his accent is almost smooth
Once again a life saver. Thanks

Very Helpful Video. Clear & Concise.Thank u Sir.
Is there a video on solving Parabolic PDEs using Implicit Method?
Yes?

your explanation is very helpful
very helpful and easy to understand, please make another video of numerical method
how to implement derivate dT/dx =0 condition in fdm method
Helped me a lot. Thank You
Spread the word about the complete resources at nm.MathForCollege.com
did the problem statement will always give us the initial value which we will take for the interior points
No, you will need to use the physics of the problem or just start with a zero value.
thankyou very much
What are other examples of parabolic pdes except heat equation?
en.wikipedia.org/wiki/Mean_curvature_flow
en.wikipedia.org/wiki/Ricci_flow
Thank you professor .
extremely helpful to me.thankyou sir
Thank you sir
where did u get the Temperature value for each interior nodes? i dont understand T,T
Temp taken value from time t=0 to t=9sec put in lemda value
its given in question 20°C
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
I also cant understand it, did you find he answer ?
i just understand it now. he already include calculation of time step in lamda. if the time step is different then lamda will be different too
two years ago probably this is not import for you right now☠
why the value of Lamda is always same with the change of t?
really good explanation thank you sir.
Thanks alot!
What is j here ?
Subscript i represents the location and j represents the time node. For example j=0 will be t=initial value of time, j=1 will be initial value of time+delta t. See nm.mathforcollege.com/mws/gen/10pde/mws_gen_pde_txt_parabolic.pdf
@@numericalmethodsguy thank you sir it helped me a lot
very good
