NumaSim Simulator

How NumaSim's editor and simulator work — the app-specific features you use to build, run, and read a study. Read these when you want to know how to drive the tool. For the underlying engineering theory (EMT, the companion-model method, nodal analysis), see Learn.

Topics

• The canvas — pan and zoom the work area and place components from the palette or by double-clicking to search.
• Running a simulation — set the time step and duration, press Run, and read the progress, warnings, and results.
• Observables — name a signal, scope it, and read it back as a column in your CSV results.
• Scope panel — adding, removing, and zooming traces while a simulation streams.
• Wire routing — orthogonal routing strategies and when each one fits.
• 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.
• Power flow — solve the steady-state load-flow of your circuit.
• Chat / AI assistant — let the built-in AI add components, wire them up, and explain your circuit.
