Is the definition of C_a_BC correct? For a 1D grid, is the behavior of
C_a.constrain(C_a_BC, where=mesh.facesRight)
with a CellVariable instead of a scalar value
C_a_BC= C_a_0*(1-X)
meaningful?

Subject: Re: Diffusion-Convection-Reactive Chemisty
I'm sorry. I was trying to fix the problem, and forgot to put a line back in,
which was masked by me not clearing a variable value for V. My apologies.
Please try this code instead. It has the traceback I mentioned before.

Hi Daniel,
It is giving a different error for me
Traceback (most recent call last):
File "ConversionModel.py", line 78, in <module>
V.constrain(V0,mesh.facesLeft)
NameError: name 'V' is not defined
Is this the correct script?
