Static (BasicStaticDriver) — Solve a time independent problem.
BasicStaticDriver is the trivial subclass of BasicStepDriver. It's used as the
time_stepper argument of BasicSolverMode when solving static or
quasi-static systems. Quasi-static systems are those in which the
beginning and end times are not identical, but
either the equations have to time derivatives, or the stepper is
static. The solution of a quasi-static system is a sequence of
static equilibrium solutions at different times.
