Should reaction be taken into account in the CFL condition when solving advection-diffusion-reaction equations numerically?
The CFL criterion is derived for convective problems usually. You may also get a similar criterion for diffusion problems (although the grid size is squared in the formula).
For the reaction however, ...

Should reaction be taken into account in the CFL condition when solving advection-diffusion-reaction equations numerically?
The CFL condition refers strictly to purely hyperbolic problems where there is a well-defined domain of dependence for the analytical solution. It state that a necessary condition for stability is ...

Should reaction be taken into account in the CFL condition when solving advection-diffusion-reaction equations numerically?
CFL is a necessary requirement for stability in transport-dominated systems, but in practice, is an intuitive way to interpret linear stability. A 1D advection-diffusion (or somewhat upwinded ...
