Discussion Overview

The discussion revolves around the possibility of independently varying the parameter Kij in two different methods related to a specific problem or equation. The scope includes technical reasoning and potential errors in calculations.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant claims to have results consistent with references in the first method but questions the second method.
  • Another participant asserts that both methods are incorrect, citing a missing factor of 2 in the first case and a missing factor of 2 in the first term of the second case.
  • A third participant acknowledges the feedback and suggests a need to consider a different Kij in their calculations.
  • One participant states that it is not possible to vary Kij independently of itself.

Areas of Agreement / Disagreement

Participants express disagreement regarding the correctness of the methods, with some asserting errors in both approaches and others questioning the independence of Kij variation.

Contextual Notes

There are indications of missing factors in the calculations, and the discussion reflects uncertainty about the independence of Kij in the methods presented.

I got the result that is consist with references in fisrt case. Is there anything wrong in 2nd way?

Both are wrong. In the first case you are missing a 2 in both terms (still giving the same equation if you put the variation to zero). In the second case you missed a 2 only on the first term.
 
Thank you. I see.

I should consider another Kij here.
 
Yes, you cannot vary Kij independently of Kij.
