This works on my machine, thanks for the fix!

Yes. The Steigenberger model Timo and Rene Gassmoeller implemented last 
Friday has both variable viscosity and density. (And Thomas's model has 
variable density.) So I think that is relatively simple.

As for refinement: if you know where you want to refine that's simple -- 
take a look at the step-1 tutorial program in deal.II, for example.
