Hi,
no the default is backward differences (implicit Euler).
You can set the mode as third template argument (of type bool) of the
FVAssembler class.
See e.g.

Dear Timo,
Thanks a lot for the quick answer, is the forward difference implemented
by default?
Regards,
Mahmoud

You can currently use Forward or Backward differences. But only first order
one-step methods are implemented.
Higher order time one step multi-stage time discretisation methods sort of work
on an experimental branch

Hello Dumux team,
I have a small question please. Does Dumux use the first order
difference quotient for temporal discretization as shown in page 32 of
the handbook v3.3 or it was just an example?
Best Regards,
