As these effects could impact SPARC operation, we are investigating whether their causes are physical or numerical. A dependence on input core power is found, indicating a power threshold necessary to trigger them. Initial conditions strongly affect steady-state currents and power-sharing in connected DN. We analyze parallel current as a potential driver, and we present a method to reach balanced steady-state solutions in DN, by initially disabling current terms in SOLPS-ITER.
