Eigenvalue problem with Dirichlet Boundary condition

Hi all,

I am a newbie of comsol and try to solve eigenvalue problem in a finite region using the PDE module. When I try to impose Dirichlet boundary condition, it seems not working. The eigen-wavefunction's value at boundary does not equal to the value I set. Even when I set u(at boundary)=1, the eigen-wavefunction appears to be 0 at boundaries. What kind of stupid errors have I made in the attachment? I am really looking forward to your response.

Thank you for your time!
