In the present report we continue the detailed B2 - B2.5 code comparison/extension activity started in [1] (Part I: Modeling Equations, Code Dis-integration) for upgrading of B2-EIRENE fusion edge plasma edge code suits from SOLPS4.3 to SOLPS_ITER. We assess the extended options to include parallel electric currents (and the electric potential) in these computational scrape o layer models. Starting from the original implementation [2] we demonstrate its full equivalence with the later introduced formulation in the B2.5 code by rstly re-deriving both sets of additional equations and boundary conditions, and then secondly carrying out a series of benchmark calculations, continuing the earlier set of reference test cases of [1] to non-ambipolar conditions. We show that also with respect to parallel electrical currents both codes an be perfectlymatched. Our tests so far are limited to single ion uid (no plasma impurities) case, sonic (M=1) plasma outow conditions, and to fully orthogonal, and even rectangular, computational grids.
