How to run adjoint optimization locally?

[triplestone0818]

Due to the limited 400 structures in the remote cloud server, is there any else way to simulate more than 400 structures with tidy3d? The method now i want to do is run adjoint optimization in my local server, but i don't know whether it is practical or not.

Yeah, actually you should be able to do from tidy3d.plugins.adjoint.web import run_local, use that instead of the usual adjoint run call, and comment out the maximum structure validator in your local code.

Thank you, this method seems to work, now there is no limit for the number of structures, so that i can simulate a large diameter metalens in my local server.

@momchil-flex I don't think that will work because our server will error due to this validator right?

[momchil-flex]

No, run_local only submits a regular Simulation, not a JaxSimulation.

One approach could be to make these "post-init" validators and only call them when we use the remote tda.web.run()? (ie don't validate this on local_run?

[triplestone0818]

Thank you your answer!

Closing this, @triplestone0818 in a future release, we will make this a bit more convenient through #1575 (so you won't need to comment out the validators manually)
