{{Note|Small values of inductance may result in the divergence of the FDTD numerical scheme. To avoid this problem, you need to increase the mesh resolution and adopt a higher mesh density. This, of course, may lead to a much longer computation time.}}

=== EM.Tempo's Simulation Modes ===
Once you build your physical structure in the project workspace and define an excitation source, you are ready to run an FDTD simulation. The simulation engine will run even if you have not defined any observables. Obviously, no simulation data will be generated in that case. EM.Tempo currently offers several different simulation modes as follows (click on each type to learn more about it):
* '''[[#Running a Wideband FDTD Analysis | Wideband Analysis]]'''* '''[[Parametric_Modeling,_Sweep_%26_Optimization#Running_Parametric_Sweep_Simulations_in_EM.Cube | Parametric Sweep]]'''* '''[[Parametric_Modeling,_Sweep_%26_Optimization#Optimization | Optimization]]'''* '''[[Building_Reusable_Models#Running_an_HDMR_Sweep | HDMR Sweep]]'''* '''[[Modeling_Periodic_Structures#Running_a_Dispersion_Sweep_in_EM.Tempo | Dispersion Sweep]]''' for periodic structures excited using a plane wave source
