Inverse Design

Both the forward and the adjoint simulations are billed when running inverse design optimizations using the adjoint plugin. That represents a significant reduction in computation cost as the adjoint method allows one to calculate the gradient of an objective function with respect to thousands of design parameters in only two simulations.

We highly recommend watching the Inverse Design lectures if you are new to the adjoint method. You can also go through this tutorial for an introduction to the basic concepts related to automatic differentiation and adjoint optimization.
