A hydrodynamic model is used to explore the nonlinear optical properties of a plasmonic gold nano ellipsoid. This simulation study reveals spherical harmonics in the near-field and vector spherical harmonics in the far-field. Higher-order susceptibility maps show that the nonlinear effects originate from the tips of the nano ellipsoid and that the second and third-order susceptibility values, stemming from the free electron response, are on the order of 10^-12 [m/V] and 10^-24 [m^2/V^2], respectively. Finally, four and five-wave mixing is simulated, showing equal conversion efficiencies to existing solutions. Wave mixing is useful for photon entanglement and quantum information applications.
