You need to explain in a bit more detail what you do and where the problem happens: - Do you compute the eigenvalues on an adaptively refined mesh? If so, are they correct *on this mesh*, and are the eigenvectors? - If so, I understand that you transfer the solution to a different mesh where things are wrong. When you visualize the eigenvectors, do they look wrong? How so? Only at hanging nodes? You should be able to test this on a coarse mesh.
