This introductory demonstration will show you the fundamental workflow of the COMSOL Multiphysics® modeling environment. We will cover all of the key modeling steps, including creating geometries, setting up physics, meshing, solving, and postprocessing. We will also highlight new features in COMSOL Multiphysics® version 5.3a.

COMSOL® Modeling of the DIII-D Tokamak Systems

The DIII-D tokamak is a plasma experimental device that employs magnetic fields to achieve nuclear fusion. A complex set of coils with up to 140 kA of current are used to create, shape, and confine the plasma. Plasma currents of 2.5 MA with magnetic fields up to 2.1 T are produced and maintained for up to 10 s.

Two external heating systems are required to heat the plasma to fusion temperatures. 20 MW of neutral beams are used to inject extremely fast neutral particles, and 4 MW of microwave power are used to generate RF waves for plasma heating and control. While the magnetic field and coil currents are typically static or slowly varying, the plasma current can collapse in a few milliseconds ("disruption") and this transient can induce forces and torques on attached structures. These effects need to be modeled and understood in order to design new systems and to calculate their operational regime.

The COMSOL Multiphysics® software with its user-friendly interface has been used to model many coils and RF antenna configurations. Its visualization capability has been valuable for solving problems and optimizing new designs. In this presentation, the magnetic field configuration in the DIII-D tokamak and its neutral beam system will be presented, and calculations of the induced currents and electromagnetic loads due to the fast plasma current disruption will be described. RF characteristics of a new antenna being developed as a plasma heating source will also be presented.

Acoustic Modeling Using COMSOL Multiphysics®

The COMSOL Multiphysics® software and add-on Acoustics Module provides powerful numerical tools for modeling and studying acoustic systems and predict factors like acoustic and noise reduction performance. An introduction to acoustic and vibration analyses using COMSOL Multiphysics® and the Acoustics Module will be presented. Two simple examples will be featured for numerical modeling purposes and will be discussed.

Coffee Break
