Towards nonaxisymmetry; initial results using the Flux Coordinate Independent method in BOUT++
Brendan Shanahan, Peter Hill, Ben Dudson
Fluid simulation of stellarator edge transport is difficult due to the complexities of mesh generation; the stochastic edge and strong nonaxisymmetry inhibit the use of field align…
Hermes: Global plasma edge fluid turbulence simulations
Ben Dudson, Jarrod Leddy
The transport of heat and particles in the relatively collisional edge regions of magnetically confined plasmas is a scientifically challenging and technologically important proble…
Dirichlet boundary conditions for arbitrary-shaped boundaries in stellarator-like magnetic fields for the Flux-Coordinate Independent method
Peter Hill, Brendan Shanahan, Ben Dudson
We present a technique for handling Dirichlet boundary conditions with the Flux Coordinate Independent (FCI) parallel derivative operator with arbitrary-shaped material geometry in…
Blob dynamics in TORPEX poloidal null configurations
Brendan Shanahan, Ben Dudson
Three dimensional blob dynamics are simulated in X-point magnetic configurations in the TORPEX device via a non-field-aligned coordinate system, using an isothermal model which evo…
A novel flexible field-aligned coordinate system for tokamak edge plasma simulation
Jarrod Leddy, Ben Dudson, Michele Romanelli +2
Tokamak plasmas are confined by a magnetic field that limits the particle and heat transport perpendicular to the field. Parallel to the field the ionised particles can move freely…
