CVODE interface

[Mohammad Mahdi Moayeri]

Hello,

I have a question about the SUNDIALS wrappers in deal.II. I can find wrappers for ARKODE, KINSOL, and IDA, but I do not see an interface for CVODE.

Is there a specific technical or design reason why deal.II does not provide a CVODE wrapper? I noticed the old issues #5027 and #5045 mentioned CVODE support, but I could not find a follow-up explanation.

Cheers,
Mahdi

Dear Mahdi,

we simply never implemented one. I found that the ARKODE interface can be used very effectively also as a replacement for both stiff and non-stiff odes. If you really want to use cvode, you could also do so through our PETSC-TS interface, that supports CVODE sundials time steppers, using time stepper type sundials.

Of course we accept pull requests if you feel like providing an interface to CVODE that follows our ARKODE and IDA interfaces! ;)
