Question - at about 13:20, you introduce that the thermal conductivity at the east face could be different than the thermal conductivity at the west face. wouldn't that indicate that k was a function of x, and would have to be handled in the integral appropriately?
Hi, Tanmay, thank you for this video, that's really usefull. I have a question about how the boundary conditions are implemented in various CFD commercial software: In particular, i have noted that OpenFoam for example, does not generate nodes on the boundaries, but instead, the boundaries are just different patches. So, is true that in most commercial cfd software, there isn't the possibility to generate points on the boundaries?
There are many ways to go about that actually. Many FVM implementations use the grid type 2 that I showed in a previous video. Some solvers might also use an extra layer of ghost cells. Honestly, I haven't looked very closely into it because every package maybe written differently
21:34 The value of hpe for boundary points will be less than interior points (maybe half) right? so value of ae also changes for boundary node. Am i right or am i missing something?
Sir if you correlate CFD theory along with ANSYS Software then we can understand that ohh here we are applying this boundary condition in software Thanks Sir

Hi Tanmay,
I'm following your lectures and just wanted to say Thanks!! :)

In openFoam the flux is calculated on the boundaries
Amazing! Thanks a lot!

Thanks Sir
Good idea. Will try!! Thanks for the suggestion.
Exactly what I wanted to say. This course is helpful also but that would complete the understanding in terms of software based implementation
