Hiya, really struggling with re-arranging the Nernst-Planck equation to specify coefficients:
In the form that PDE Toolbox requires:
I understand that:
m = 0
d = 1
f = 0
But besides that I have no idea how to specify co-efficients 'a' and 'c' to form this equation, due to the addition of the electric field component.
Any wisdom much appreciated!!
