Abstract
Full Wave (FW) studies of mode conversion (MC) processes in toroidal plasmas have required prohibitive amounts of computer resources in the past. The TORIC code solves the linear fourth order reduced wave equation in the ion cyclotron range of frequencies (ICRF), in toroidal geometry using a Fourier representation for the poloidal and toroidal dimensions and finite elements in the flux dimension. It has been parallelized to increase available computer processing and memory. Mode conversion scenarios may now be done routinely in a few hours of elapsed time with 32 processors. We present examples of fully converged studies of MC on Asdex‐Upgrade and Alcator C‐Mod. The new capabilities of the code extend beyond what is required for ICRF MC and permit studies of the very small wavelengths of lower hybrid (LH) waves. We will show preliminary results of FWLH calculations in C‐Mod geometry.
