It looks right to me. What's the problem?
I am not sure what kind of result was displayed on your computer.
The result I see with the gist viewer is exactly what's shown in your
schematic (page 1 of 2), rather than what's in your graph (page 2 of
2). I've printed out the values with the TSVViewer just to be sure.
Therefore, what you're seeing are display glitches with the
matplotlib viewer, not problems with the initial conditions you are
setting.
The picture I got from the code is in the PDF file as attached. I
have three questions with respect to this result:-
Q1: The concentrations in A1 and A2 are set the wrong way. Area A1
should be Calpha0, and Area A2 should be Cliq0.
The actual values are correct. I don't know why matplotlib is
displaying them wrong.
Q2: The concentrations in Area A3 and A4 should be homogeneous, but
they are obviously not.
By homogeneous, I assume that you mean that A3 and A4 should have the
same value. If you use a different viewer or print out the values,
you'll see that they do have the same value, so this is another
display glitch.
Q3: Even in Area A3, the concentration seems not homogenous, why
does this happen?
matplotlib tries to be helpful and smoothes the transitions between
different color regions. With finer resolutions, this isn't that
noticeable and actually produces better looking graphics, but it's
clearly deceptive here. We'll look into a way to turn it off.
We will investigate what's going wrong with matplotlib. I do see the
same thing here.
