How are global evaluations of the displacement field done in a solid mechanics simulation?

I am doing an eigenfrequency study of a solid mechanics system. I have defined some variables, let's call them A and B, which depend on the "solid.disp" variable from the "Solid Mechanics>Linear Elastic Material" node (that is to say, the mechanical displacement magnitude) and the "displacement field", the dependent variable in the "solid mechanics" node. I then evaluate A and B under a "results>derived values>global evaluations" node. Now my question is, how will A and B be evaluated? The mechanical displacement should change as the mechanical system resonates, right? So is the solid.disp used in the global evaluation the maximum of the displacement magnitude or is it something else?

I am asking because I expect A > B and instead get A < B so maybe I am missunderstanding something about how the variables are evaluated. For both variables, A and B, involves an integral over the same spatial domain and B involves a derivative of the "displacement field".
