Implementation of drift velocities and currents in SOLEDGE2D–EIRENE

•Derivation of electric potential equation for the transport code SOLEDGE2D–EIRENE.•Inclusion of drifts and currents in SOLEDGE2D–EIRENE.•Tests in simple configuration.•Application to WEST divertor configuration in Forward and Reverse B field. In order to improve cross-field transport description, drifts and currents have been implemented in SOLEDGE2D–EIRENE. The derivation of an equation for the electric potential is recalled. The resolution of current equation is tested in a simple slab case. WEST divertor simulations in forward-B and reverse-B fields are also discussed. A significant increase of ExB shear is observed in the forward-B configuration that could explain a favorable L-H transition in this case.
