| Dec 21, 2023 at 8:31 | comment | added | Amilox Lex | Thank you for the reply @ConvexHull. It seems to me that you took the derivative of the solution vector at the boundary point, then you divided it with the corner value of the differentiation matrix and then subtracted it from the boundary point of the solution vector. Can you please explain how you derived that expression? I don't understand why that boundary point adjustment works. Why is the subtraction from the boundary point done like that and why do the dividing with the corner element of the differentiation matrix? What would change if the boundary condition wasn't homogeneous? | |
