Package Structure
=================

Here, we dive deeper into the structure and architecture of PathSim.



Object Hierarchy
----------------

The basic object hierarchy of PathSim is shown in the diagramm below.

Available Solvers
-----------------

The numerical integrators, available in PathSim are structured like this:

They are implemented from scratch to expose their interfaces to the PathSim simulation loop. The integrators are validated against reference problems in the test suite.
