Solving 1D Convection Diffusion Equation using MATLAB | Lecture 11 | ICFDM

[@AbdallahMRagab]

Welcome back, Thanks...

[@rohitsvarma3562]

also why are a_p, a_w and a_e defined inside the loop?

[@rohitsvarma3562]

is (rho*u) constant i.e is Fe=Fw?

[@dhananjaykumar1627]

Can you give me the idea to solve the 3D species transport equation for steady state? I am facing the problem with convection term which include Peclet number. If possible kindly suggest me to solve using the FVM because through the FDM, with increasing Peclet number beyond 10, always divergent is coming.

Great works!

Explain Matlab Code for QUICK scheme for 1 d Convection Diffusion equation.

[@royvarghese823]

Great video but your code is not working in CDM part

Hai sir. It is really a worth lecture. But i am getting confused with boundary nodes. Can you please explain how this codes are doing at boundary nodes?

[@AhmarFarman]

bro boundary nodes are different the answers are coming wrong do you have the correct codes

[@AhmarFarman]

cant take those at phi (1) and phi(n). can you help

[@AhmarFarman]

I need the code. I have tried using different boundary nodes but still.

[@AhmarFarman]

do you have the correct code

Dear Tanmay Agrawal, happy new year, well done for great job done on your channel. Please, my numerical solution does not converge (it is not giving a linear line), only exact solution. I used your code word to word, what could be the issues. Thank you

[@TanmayAgrawal7]

Can you email your query?

[@godwinekunke7075]

@@TanmayAgrawal7 your email address please. Thanks a Million Sir 🙏

Sir, while writing the exact solution in Matlab, the multiplication sign is different (I mean there is a dot (.) in front of multiplication), can I know the importance with and without the dot symbol during multiplication or division operation???

[@rajivverma2264]

A.*B means that the terms of the matrix A and B are being multiplied with each other.

[@8fawzy]

hi, could you give us the code please?

[@ALOKSRK1]

Sir's look same as lecture 1, like coding 😂😂😂😂😂😂😂😂

[@TanmayAgrawal7]

This is lecture 1_1 😀
