In the below equation, I don't understand well how FiPy solves
convection when the convCoeff is a function of
concentration. I believe
that one needs to factor out one concentration term from a convCoeff when it is a function of
concentration. Is my understanding here even correct?
If it is, I'd like to understand this
better. I can't seem to find
anything in the manual or reference guide that explains that
FiPy includes the concentration in the below equation, and it needs to therefore be factored out in some
cases. If this is something that is known to one skilled in the
art, please say so (or point me to a
reference that might explain it). If
it is a unique feature of how FiPy solves things, could you perhaps elaborate further in
future manual and reference materials. Is this true for all ways of
solving convection (i.e. PowerLaw, Hybrid, etc.). Does the diffCoeff also
need to have concentration factored out?
\begin{equation}\nabla\cdot \left[ConvCoeff\nabla \phi \right] \end{equation}
Thanks for your
time.
