In this learning track, we will learn about Ansys Lumerical FDTD and see how to set up, run and analyze a simulation. We will first discuss the underlying solver physics and numerics of Ansys Lumerical FDTD, the types of problems it can solve, and how it can be best used for parallel computation. Then we will learn about the default materials and material models, as well as how to add additional materials to the material database. Following this, we will take a look at the Ansys Lumerical FDTD solver region object which is used to specify the simulation time, the simulation region, mesh, and boundary conditions. We will also learn about the available types of sources and the various types of monitors, and their recommended usage in Ansys Lumerical FDTD. Finally, we will learn how to view simulation results, plot, and export data, how to perform additional post-processing of monitor results using analysis groups, and how to verify the accuracy of simulation results in Ansys Lumerical FDTD.
