Developer Guide

These pages describe how DPsim is built rather than what it computes. They are the background for adding a component, changing a solver, or working out why a simulation behaves as it does. For the physics and the numerical methods, see concepts.

Two ideas run through the codebase and are worth reading first. Attributes expose component parameters and state to the logger, the Python bindings and the scheduler. Tasks carry declared attribute dependencies, and those declarations are what the scheduler uses to order and parallelise a timestep.
