“…Generating the mesh in this framework is a task specific to fusion plasmas, especially for diverted plasmas with one or several X-points. Most codes rely on dedicated grid generation strategies in the 2D poloidal cross-section [74] and tools [76,77], and this 2D mesh is simply extruded in the toroidal dimension to obtain the final 3D mesh. Though advantageous, the latter meshing strategies are not capable of taking advantage of the quasi-2D nature of the tokamak plasma turbulence : typically, in a conventional 3D curvilinear mesh, the quasi-aligned character of turbulent fluctuations imposes that number of grid points N ϕ is linearly related to the number of grid points in the poloidal direction N θ by…”

“…The second step of this process is generating the XPT grid mesh from an equilibrium. To do this, we have used INGRID [21], an open-source grid generator than can use snowflake and X-point target equilibria, among others.…”

The design and understanding of alternative divertor configurations may be crucial for achieving acceptable steady-state heat and particle material loads for magnetic confinement fusion reactors. Multiple x-point alternative divertor geometries such as Snowflakes and X-point targets have great potential in reducing power loads, but have not yet been simulated widely in codes with kinetic neutrals. This paper discusses recent changes made to the SOLPS-ITER code to allow for the simulation of X-point target and low-field side snowflake divertor geometries. Snowflake simulations using this method are presented, in addition to the first SOLPS-ITER simulation of the X-point target. Analysis of these results show reasonable consistency with the simple modelling and theoretical predictions, supporting the validity of the methodology implemented.
