Component and Solver Initialization
How DPsim initializes components and solvers before the first simulation timestep.
Writing a Model
Adding a component, interfacing it with the solver, and finding out why it is wrong.
The path from an empty file to a working component: what to declare, which hooks the solver calls and in what order, how a component built from other components is assembled, and how to debug one that runs but produces the wrong answer.
For the equations a model should implement, see Concepts. For worked examples of finished models, see model implementations.
Real-Time Execution
Tuning the host and writing a model that can hold a deadline.
Interfacing with the MNA Solver
The hooks a component implements to take part in the nodal solve.
Subcomponent Handling
Building a component out of other components with CompositePowerComp.
Add New Model
Extending the simulator with new component or control models.
Create New Simulation
Using DPsim for a new simulation scenario.
Debugging
Finding the cause when a simulation runs but produces the wrong answer.
Logger Implementation
The classes called a logger, and the seam for adding another.
