N2 - We explored the possibility of using FEM (finite element method) to plasma wave simulation in LH/ICRF frequency regimes. A FEM based full wave lower hybrid wave simulation code, LHEAF (Lower Hybrid wavE Analysis based on Fem) code is connected to 3D Fokker-Planck code to evaluate LHCD profile. In the Fokker-Planck analysis, the quasi-linear diffusion is evaluated based on the transit-acceleration during one bounce time. The comparison of the calculated current profile on Alcator C-Mod shows reasonable agreement with the equilibrium reconstruction which is constrained both by kinetic and motional Stark effect (MSE) pitch angle measurements. In addition, a method to integrate edge/antenna simulations using FEM with a core plasma code is sought, showing interesting possibility (presented in the poster).
