Conduction - finite difference method

Click For Summary

Discussion Overview

The discussion centers around the application of the finite difference method in solving a conduction problem, specifically in a homework context. Participants are exploring different approaches to the problem and seeking guidance on how to correctly apply the method.

Discussion Character

  • Homework-related, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses confusion about their attempts to solve the problem using the finite difference method and requests guidance.
  • Another participant asserts that the first approach yields the correct answer, questioning the initial claim of being wrong.
  • A third participant reiterates the assertion that the first approach is correct but cites feedback from an instructor regarding the interpretation of temperature data and its relation to the finite difference equations.
  • One participant admits to not understanding the instructor's comments, indicating a lack of clarity in the discussion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the correctness of the approaches discussed. There are competing views regarding the validity of the first approach and the interpretation of the instructor's feedback.

Contextual Notes

There is uncertainty regarding the interpretation of the temperature data and its relevance to the finite difference equations, as well as the specific requirements of the homework problem.

I have tried two different approaches, but still i am wrong in the question. Can anyone guide me how to attempt this question?
Thank you

The first approach gets the right answer. Why are you saying that it's wrong?

The system says I am wrong (ref: first screenshot in #1), and the following is what my instructor says:
"Are these temperatures computed by you, by solving the finite difference equations ? If these are given in the problem, these are for input data corresponding to the case of delta x = delta y."
I have no clue in understanding how should I do it...
Thank you.
 
Sorry. I have no idea what he's getting at.
