Unformatted text preview: condition is effectively implemented. Thus we see that it is quite easy to implement a general-geometry 1-D diffusion code.
Zero Flux Boundary Condition
When we analytically calculate eigenvalues with an extrapolation distance of 2D, we set the
eigenfunction to zero rather than the linear extrapolation of the eigenfunction. For instance, let
denote the left boundary coordinate. We analytically set
( ) ( ) ( ) Rather than setting
() () Eq (11a) approximates Eq (11b), but they are not equivalent. Satisfying Eq (11a) numerically is possible,
but not easy. However, the zero-flux bounda...
