* Select the simulation mode and run the FDTD engine.

For certain problems, more than one combination or choice of settings and [[parameters]] may still give acceptable results. In most cases, EM.Tempo tries to make these choices convenient for you by suggesting default settings or default parameter values. For example, EM.Tempo by default generates an "adaptive" type mesh with a default density of 20 cells per effective wavelength. The default computational domain features CPML walls placed a quarter free-space wavelength away from the large bounding box of the entire physical structure. A modulated Gaussian waveform with preset optimal [[parameters]] is used to drive the project's excitation source by default. You can change most of these settings arbitrarily. For example, you can set up your own computational domain with different types of boundary conditions, customize the FDTD mesh by modifying a large number of mesh settings and use other types of excitation waveforms.
