In this course, we will briefly explain what Ansys Lumerical varFDTD is and how it works. We will introduce some key example devices where the varFDTD solver can be used.
In this course, we will discuss the effective index method used by the Ansys Lumerical varFDTD solver to collapse a 3D geometry into a 2D simulation. The course starts by describing the simulation workflow, which highlights some of the differences between varFDTD and a traditional FDTD simulation. After the workflow is introduced, more information will be provided on the algorithm used to compress the simulation into an effective 2D simulation.
