Abstract
The broad scientific objectives of the SWIM (Simulation of Wave Interaction with
MHD) project are twofold: (1) improve our understanding of interactions that both radio
frequency (RF) wave and particle sources have on extended-MHD phenomena, and to
substantially improve our capability for predicting and optimizing the performance of burning
plasmas in devices such as ITER: and (2) develop an integrated computational system for treating
multiphysics phenomena with the required flexibility and extensibility to serve as a prototype for
the Fusion Simulation Project. The Integrated Plasma Simulator (IPS) has been implemented.
Presented here are initial physics results on RF effects on MHD instabilities in tokamaks as well
as simulation results for tokamak discharge evolution using the IPS.
