Concepts

The ideas behind NumaSim's editor and simulator. Read these when you want to understand why something behaves the way it does, not just how to use it.

Topics

• EMT simulation — what electromagnetic-transient simulation is and the companion-model idea behind it.
• Nodal and modified nodal analysis — how each time step's linear network is assembled and solved.
• Observables — name a signal, scope it, and read it back as a column in your CSV results.
• Power flow — solve the steady-state load-flow of your circuit.
• Subsystems — wrap a sub-circuit in a container that runs at its own time step.
• Multi-rate monitoring — view fast and slow signals together on the same scope.
• Wire routing — orthogonal routing strategies and when each one fits.
• Scope panel — adding, removing, and zooming traces while a simulation streams.
• Chat / AI assistant — let the built-in AI add components, wire them up, and explain your circuit.
