Do I need to do something different from the normal loop over elements and DOFs for integration when using Hierarchical elements of order >3? I'm evaluating a matrix of which I find eigenvalues. This works for order <=3 for Hierarchical and Lagrange (<=2) on HEX27 geometry. When I switch to order 4 Hierarchical on the same geometry, I stop getting any eigenvalues for the matrix in the same range.
