Hi,
Actually I don't have a problem with fipy when solving my equations, my
question was about how to express my boundary conditions for the second
equation. It was a mathematical question rather than a question about
fipy. Thanks Daniel,
Fadoua

Does FiPy work for you
Hi All,
Thanks Daniel for mentioning that. Actually I'm using the simple diffusion
equation
\frac{\partial b}{\partial t} = D \frac{\partila ^2 b}{\partial x^2}
with initial condition
b(x, t=0) = b0 constant for 00
b(x=L, t) = 0 for t>0
This means that once the particles reach the boundaries the

Hi All,
I have particles that diffuse in one dimensional space, but once they
reach the boundaries (x=0, and x=L) they get stuck and do not come back to
the free space. Please, Does anyone of you knows how can we express that
in terms of boundary conditions? and how can we measure how many particl
