The gyrofluid electromagnetic (GEM) model studies the phenomena in the context of edge turbulence, a matter of adding collisions and electromagnetic induction to the parallel dynamics of the standard six-moment toroidal model, the use of which was done in core turbulence works. Currently, the code describes the fluctuation free-energy conservation in a gyrofluid model by means of the polarization...
The purpose of the Fusion Simulation Project is to develop a predictive capability for integrated modeling of magnetically confined burning plasmas. In support of this mission, the Center for Plasma Edge Simulation has developed an End-to-end Framework for Fusion Integrated Simulation (EFFIS) that combines critical computer science technologies in an effective manner to support leadership class computing...
Artificial Bee Colony (ABC) algorithm is an optimisation algorithm based on the intelligent behaviour of honey bee swarm. In this work, ABC algorithm is used to optimise the equilibrium of confined plasma in a nuclear fusion device. Plasma physics research for fusion still presents open problems that need a large computing capacity to be solved. This optimisation process is a long time consuming process...
In this work we describe an optimization technique for PIC/MC modeling of the plasma edge using High Performance Computing. The developed code BIT1 can be used for 1D3V plasma and 2D3V neutral particle modeling with a reasonable scaling up to 1000 and more processors.
As computing capabilities have increased, the coupling of computational models has become an increasingly viable and therefore important way of improving the physical fidelity of simulations. Applications currently using some form of multicode or multi-component coupling include climate modeling, rocket simulations, and chemistry. In recent years, the plasma physics community has also begun to pursue...
Calculating neoclassical (NC) transport is a fundamental part of the complete simulation cycle of the behavior of plasmas inside all tokamaks and stellerators. Also, due to NC transport is mainly determined by the magnetic properties of the device, its study is mandatory to ensure the efficiency of a certain coil configuration before it is implemented in a Fusion reactor. Thus, improvements to already...
One of the central tasks of EUFORIA is to port, parallelise, and optimise fusion simulation codes, developed at individual research institutes in Europe. There are three supercomputer centres involved in the project located at Barcelona, Edinburgh, and Helsinki. For some of the fusion codes simply porting them to one of the supercomputers represents a major advancement in the use of the codes, as...
FAFNER is code developed by Lister which simulates by Monte Carlo methods the Neutral Beam Injection (NBI) technology, one of the most extended heating methods for fusion devices. To the date, FAFNER has been usually run at CIEMAT adapted to the TJ-II helical axis stellarator on shared memory Cray architecture machines. From this version, FAFNER has been ported to the Grid in the framework of the...
