W7-X edge modelling with the 3D SOL fluid code BoRiS

BoRiS is a 3D scrape-off layer (SOL) transport code under development which is to solve a system of plasma fluid equations. BoRiS is currently extended towards a physics model including continuity, parallel momentum and energy equations for both electrons and ions. In addition the code requires the implementation of adequate solvers and the generation of high precision metric coefficients throughout the entire computational domain.
