Dear Wolfgang,

Thanks for your quick reply. Are there any additional changes like this in
the numerical methods?

Looking forward to reading the follow-up paper.

Well, I was just wondering, as I couldn't find where in the assembly.cc
the output of 'bdf2_extrapolate' was used. In the paper these terms only
occurred in the rhs of the energy equation (page 18, def of G_i), I think.
