# Device simulation reference¶

All functions and classes related to device simulation are namespaced under i3.device_sim.

For a tutorial running device simulations with IPKISS, please check the running device simulations tutorial.

 device_sim.SimulationGeometry Defines the geometry of the electromagnetic simulation. device_sim.SMatrixOutput Output an SMatrix device_sim.LumericalFDTDSimulation Define a simulation for use with Lumerical’s FDTD Solutions. device_sim.CSTTDSimulation Define a simulation for use with CST Studio Suite (Time Domain solver). device_sim.Port A combined monitor and source, for use in a physical solver device_sim.Macro Defines a tool-specific macro which will be executed at a specified stage device_sim.MacroFile Defines a macro to be loaded from file
