Unstructured Mesh tools for Fusion Energy System Simulation Codes
POSTER
Abstract
Historically fusion plasma simulation codes have employed structured grid methods that are effective for dealing with simplified geometric regions. However, structured mesh methods are not well suited for the design of the geometrically complex components of the upcoming commercial fusion energy systems such as divertors, baffles, RF antennas, etc. Therefore, a substantial number of the developers of fusion energy system simulation codes are employing unstructured mesh methods. This poster will present a set of tools developed to support unstructured mesh fusion energy system simulation codes. The poster will present:
A set of tools that combination multiple methods to meet the specific mesh generation requirements of selected fusions simulation codes.
An infrastructure to support parallel adaptive unstructured mesh simulations that has been applied to core plasma and tokamak RF simulations.
An unstructured mesh infrastructure to support massively parallel particle in cell simulations that has been used for impurity transport and edge plasma simulations.
An infrastructure for the in-memory coupling of massively parallel fusion energy systems simulation codes that employ unstructured and structured mesh methods.
