Analysis
-----------

The analysis specification controls *what* a charge simulation computes: the
DC (and optional small-signal AC) sweep. Attach one of these to
``HeatChargeSimulation.analysis_spec``. The solver itself is selected separately
via ``HeatChargeSimulation.use_accelerated_solver``; convergence and tolerance
settings are covered under :ref:`charge-accelerated-solver`.
