Ole Elvetun is still having a problem:
I tried typing "%reset", but that didn't help.
When running from command line, it works, but I assume that in this
case, everything is totally forgotten, but it doesn't seem that way when
running from iPython, even though I clear everything out(which is really
weird!).
The reason why I'm bothered by this, is because I have to call the
solver several times when I'm computing the Hessian of a cost-
functional, and the same effect takes place here. That is, the solver
gets really messed up at repeated calls, and I don't see how I can avoid
this.
Just as additional information: I tried using Krylov-solver with ILU-
conditioning on a somewhat similar problem(not this one, but one with
subdomains and neumann conditions), and when calling first time, I
always got the same solution, but when calling repeatedly, it
"converged" at zero iteration to u = 0.
