Eigenvalue equation - numeric problem

The differential equation is an eigenvalue equation on the generic form in comsol with a,c and d_a being the nonzero coefficients. The difference between the differential equation on the three domains is the value of the coefficient a.
When I ask COMSOL to solve the problem it gives me a solution that suggests that there is something wrong with the way I have set up the problem. Can anyone see what I did wrong and how I could fix it to give the correct solution?
Secondly, I want to add a another study that solves the Poisson equation in this geometry for some specified electron density. Is that possible to add? I am not sure how to add a second study.
Edit: I have now added a second differential equation which is Poissons equation for the same geometry. I want to solve this in a second study but if I click on add study nothing happens. What should I do?
