Two simulations, the forward and the adjoint one, are performed when running inverse design optimizations using the adjoint plugin.

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.
