Eigenvalue analysis in 4.0a

Hello everybody,


I am trying to switch from 3.4 to 4.0a. For now, I am only searching for solutions of Helmholtz' equation for Dirichlet Boundaries and certain eigenvalues, e.g. \Delta \psi + \lambda^2 \psi = 0.

In 3.4 I could just set one parameter in the "Subdomain Settings" to lambda^2 and everything worked for me.

Where can I do this in the new version; I simply cannot find a field to define the eigenvalue the program should solve for?

Thank you in advance


Robert
