I have been working in 3.5a for a few years now, but have recently started a new project and decided now was the time I should upgrade to 4.2a. In 3.5a, when I had a model of a coupled system of a shell and a solid. I could set the solver to solve for eigenfrequencies on the shell and a frequency response solver on the solid. This would allow me to see purely see the eigenfrequencies generated by the shell structures and how these have effected the solid structure by plotting the displacement on the subdomains. Can this be done in 4.2a or 4.3 (I am about to upgrade again)? At present I am getting many more eigenfrequencies generated than I am interested in.

Hope that makes sense.
