eigenvalue question in COMSOL 4.0a

Dear COMSOLers,

I'm trying the COMSOL 4.0a recently, and I encounter some questions.

1. In COMSOL 3.5 and Matalb, the .m file is so clear, and I can save any data I concered. for example, in eigenvalue module, I can save the eigenvalue using "e(:) = fem.sol.lambda(:)" in .m file. But, In COMSOL 4.0a, there is no fem.*** structure, and I'm confused the new .m structure named “model” that COMSOL bulit. I cannot find any data in "model", So anybody know how can save the eigenvaule data?

2. The question is about the acoustic_structure interaction. when I using the eigenvaule ansysis, all of eigenvaule equals NaN. It's so werid. The attach is the simple model I bulit. Did I miss something?

Best wishes!

Kyo
