I apologize for posting about this PDE many times over the past few days, but I am pursuing several different approaches and each comes with its own issues. The system is given by: \begin{gathered} \frac{\partial c_{1}}{\partial t}=\frac{1}{\varepsilon}\left[f c_{2} \frac{q-c_{1}}{q+c_{1}}+c_{1} …

Only explicit solvers work for stiff PDE-derived ODEs, stiff solvers crashing

Won’t that kind of production term have explosive growth for values near 1? Are you sure that size of the initial conditions makes sense?
