If I understand it correctly, that is equivalent to solving Ax = b, with A
and b given, and x returned?

Maxi,
The interface for TimeStepping::evolve_one_time_step is:
virtual double
evolve_one_time_step(
std::vector>
& F,
std::vector> &J_inverse,
double t,
double delta_t,
VectorType & y);
and does not depend on UMFPACK at all. You just need to provide a
function-type object that can
As far as I understand all implicit time-stepping methods in the
TimeStepping-namespace take a function which invert the jacobian matrix and
the mass matrix (combined). This is done using a sparse solver (UMFPACK).
Is it that still possible for a larger system (10kk DoFs), or do I have to
resor
