Are all three methods supposed to be equivalent? I'm not sure what
exactly is wrong. Everything seems to be working as far as I can tell.
The third method has a gradient of -2.0, which is the initial value of
BC_Left and BC_Right as expected. gradExteriorValue is never updated
in the loop so it wo
Thanks for your help!
Three methods are implemented.
#1: explicit method
#2: source term + setvalue in loop
#3: source term (revised)

Post your script and I'll take a look.

Thanks for your suggestion.
However, it did not work.
The values at boundary were diverged!

Hi, everyone,
I am a newbie fipy user. Thanks in advance.
I have a simple 1D grid problem for materials diffusion.
Because the flux is determined by various non-linear functions, I
transformed the simple diffusion example to source term for the flux.
I got the same result between the explicit diff
