Inverse design of y-branch, using the lumerical example. When 2.5D parameter optimization is run, only one iteration is stopped, and the results described on the official website cannot be obtained. The following prompts appear:
and running 3D parameter optimization is normal, other similar examples are normal, have you done this example to point out the reason, thanks to

May be caused by incorrect parameter optimization Settings. You can check the parameter tuning Settings to make sure that they specify the tuning goal correctly, as well as the number and length of the tuning steps. In addition, you can check the termination conditions of the optimization to make sure that they are set loosely enough so that the optimization has enough time to reach an optimal solution.
