Thanks for your thoughts on this. I have tried to use iterative solvers,
but they all seem to fail after at some point,
Yes, you need good preconditioners!
and it seems that the
maximum number of iterations in every one of them is capped at 10000.
No, you can select that in the SolverControl object. But if you need
more than 10,000 iterations, then that really is no longer efficient.
Best
