New open computational resource for plasma processes modelling

Abstract

The paper describes a new open access computing resource nfusion.cs.msu.ru. The resource includes modules for calculating equilibrium, vertical stability, plasma evolution, simulation systems for magnetic diagnostics, as well as a new algorithm for constructing three-dimensional tetrahedral meshes in areas of complex structure. The modules are integrated into a unified software environment designed for numerical support of experiments on tokamak installations. The possibility of accessing the calculation modules on the server via the Internet, data exchange and the issuance of calculation results in the form of files, figures, and tables has been implemented. The resource supports the simultaneous operation of several users and has an information support system in Russian and English.

Application of integrated simulation environment SIEMNED to the analysis of the MEPHIST-0 tokamak operation

“…In our subsequent calculations the vacuum chamber was approximated by a discrete set of 34 filaments, and they are shown in the same figure. Devices) is a software and information environment for developing virtual analogues of complex technical devices [5][6][7]. This system is tested primarily on tokamak plants, but in the future, it is planned to expand the range of applicable devices.…”

“…This system is tested primarily on tokamak plants, but in the future, it is planned to expand the range of applicable devices. SIEMNED is based on the Virtual Tokamak software library [5], but its capabilities have been significantly expanded. To date, SIEMNED is a web-based system that includes computational code launchers and automated data exchange tools, as well as a database for storing information about devices, experiments, and calculation results.…”

“…In the calculations, a new software environment SIEMNED was used, which is being developed as a system for integrated modeling of processes in tokamak facilities [5][6][7]. To date, the unified software environment includes numerical codes for calculating the equilibrium, stability, and evolution of plasma in tokamak facilities [4,8,9]; a code for generating three-dimensional grids in regions of complex shape [10]; and a structure and database for developing the information and service.…”
