Subject: Re: Incorrect Face Value for Neumann Boundaries
On Tue, Nov 18, 2014 at 2:32
I recently noticed that the faceValue of a variable is incorrect when a
Neumann (constant gradient) boundary condition is applied. For example,
let's assume the following:
dx = 1
nx = 5
dTr/dx = 4 for right face
Tl = 300 for left face
x = [0.5, 1.5, 2.5, 3.5, 4.5]
The steady solution to this

What would be the ill effects of putting a hook in the code that would
make the boundary values correct? It would be a simple extrapolation using
half the cell width and the gradient in the cell.
I don't think it
