[petsc-users] TS problem: runge-kutta gives 0 step-length

[Juha Jäykkä]

Hi list!

I have a small problem with running a TS program with -ts_type runge-kutta. It 
keeps telling me

Very small steps: 0.000000

from the very beginning and never gets anywhere. The programs works fine for 
other TS types (well, at least euler, beuler, cn and gl).

I am out of ideas as to why this happens. I even checked the RK source code. 
Any ideas?

Cheers,
Juha
