[petsc-users] Any TSGL examples, or higher order BDFs?

[Mark Lohry]

I'd like to use a 3rd+ order BDF with TS, which appears to only have 1st 
order (backward euler/TSBEULER), and then the bindings to SUNDIALS. I'd 
like to avoid SUNDIALS as it looks like it forces the use of it's own 
non-linear solvers.

Am I correct in thinking the preferred way to construct a BDF with TS is 
to use TSGL? Are there any examples of TSGL in use? I'm not seeing any 
in the docs.
