Dear all ,

I'm optimizing a waveguide structure and I am using the trust region framework with the sensitivity analysis and fast reduced order model frequency domain solver , but in most of the cases I get this error :

Non-contiguous UIDs detected. This effect might be caused by internal waveguide ports. The 'move mesh' and 'structure sensitivities' features currently do not support internal waveguide ports.

may I know what causes this problem an how I can fix it ?
