RF Modeling and Simulation using the IPS system

The Integrated Plasma Simulator (IPS) is a computational framework that permits serial and or parallel simulation codes to function inter-operably on the most advanced massively-parallel computers so as to provide a flexible capability for integrated, multi-physics simulation. In a joint effort between the Advanced Tokamak Modeling (AToM) and RF SciDAC projects some of the most capable RF code are being made openly available using the IPS. Examples will be shown using the GENRAY, CQL3D, and TORLH codes and how these can be coupled together and also with other non-RF codes. A workflow with which TORLH iteratively coupled with CQL3D was used to study lower hybrid current drive in EAST tokamak will be described.
