The eigenvalue transform is not supported

Hi, everyone Sorry to bother you a few moment. Hi, everyone Sorry to bother you a few moment. # I got a problem that's "The eigenvalue transform for Mode analysis is not supported by all physics it solves for - Physics: Solid Mechanics (solid)" I want to build a model to simulate a relationship between optical mode and thermal expansion of geometry; In other words, I want to know if a special fiber like photonic crystal fiber thermal expanded when changing temperature whether transmission mode would be influence.
In step2: Mode Analysis under Study, I choose both solid mechanics and EM wave, then I compute the model. Here comes the problem about "The eigenvalue transform for Mode analysis is not supported by all physics it solves for - Physics: Solid Mechanics (solid)" Do anyone know how to fix this question? or could give me a similar example?

Many Thanks...
