hi Wolfgang, 

I am very happy and speechless about such figures. Well done !

There are a number of possibilities for this, and I implemented all I could think of -- with dramatic results: much smaller over/undershots of the pressure at places where the viscosity jumps, and 10x faster solves even for realistic models.
