Any other comments about this? I'm still thinking about it.
Also... does anyone (Jed?) know how to advance and explicit system alongside
an implicit system with TSGL? What I mean is that I'm solving a transient
nonlinear implicit system... but I also have a system of explicit variables
that I drag along that also get updated all the time (they are ODE's
essentially that I have analytic solutions for). I already know that if I
don't integrate those in time the same way I integrate the implicit system
then I get a degradation in time error order.
Any ideas?
Thanks!
Derek
