The oscillation field is measured by a new technique based on the projection of our simulation data onto the theoretical g-modes solutions of the associated linear eigenvalue problem. This allows us to determine both the excited modes and their corresponding amplitudes accurately.4 pages, 2 figures, proceeding of the Porto conference "Asteroseismology Across the HR Diagram", edited by M.J.
