Has anyone used DVODE and is it good?

Thanks @oscardssmith !
I see that FLINT and RKC does not explicitly require Jacobian, but they are not particularly suitable for stiff problem.
Uhm in your experience, how do you switch between non-stiff and stiff ode solver?

How to switch between non-stiff ODE solver and stiff ODE solver?

Dear all, I know many of you have very decent experience in Fortran ODE solvers. But most ODE solver are either only for non-stiff ODEs or just for stiff ODEs. I only see LSODA in ODEPACK actually can automatically switch between non-stiff and stiff methods. In general, I found that the performance of LSODA is actually not bad and it seems faster than DVODE. Also can see below, Choosing a Solver — Odes 2.6.2 documentation (scikits-odes.readthedocs.io) But perhaps CVODE may be even better. H…

Because in real case, even if we use the same model of ODE, if some parameters of the ODE changes, the problem may become a stiff problem. Therefore being able to efficiently switch between non-stiff and stiff can be very useful.
