Nodal finite element formulation is utilized to obtain discretized Helmholtz equations under appropriate boundary conditions. The hierarchical p-version nodal elements are used for meshing the cross section of wagon wheel fiber. The fiber material has been chosen to be LiTaO3 to provide proper second harmonic generation. Propagation of generated second harmonics for two incident field amplitudes are studied in this work.
