/j7YuD This is again not the solution
of \varphi for a given time but the convolution of \varphi with a
weighting distribution over time.

Jonathan, Thank you for your help.
I have a few more questions:
1)
I want for the H(\alpha, t) function to be automatically updated as
the Variable t changes. But I have a problem: The value of H is
defined piecewise, meaning that I have a treshold \epsilon. Depending
on whether \alpha <= \epsilo
First of all: Thank you so much for your help!

Hi,
I'm having some problems with solving a PDE using FiPy. The equation
is of the form:
C * \frac{\partial \varphi(\alpha, t)}{\partial t} = \frac{\partial^2
\varphi(\alpha, t)}{\partial \alpha^2} + \frac{\partial}{\partial
\alpha} (\frac{\partial H(\alpha, t)}{\partial \alpha} *
\varphi(\alpha
Thank you very much for your help :)

Hello,
I'm using FiPy to solve a Convection Diffusion Reaction Equation (one
spacial dimension, plus time). I want my source to:
da^2(H(a, t)) * P(a, t)
Where da^2(H(a,t)) is the second special derivative of a function H (a
known function and NOT the function I'm solving for) and P the
function
