3D Scrape-off layer modelling with BoRiS

The 3D fluid transport code BoRiS is applied to a hydrogen plasma and a neutral fluid in a stellarator-like geometry equipped with a poloidal ring limiter. The results demonstrate the capability of dealing with 3D effects which can be related to both the influence of the geometry and the plasma–neutral interaction as well. The setup used has similarities with a poloidal gas target in a fusion device.
