A new framework of core-edge-SOL transport simulation has been proposed. In this work, a set of transport equations applicable on both core and SOL region is formulated and a concept of a numerical scheme connecting 2D transport code and 2D equilibrium code is also proposed. This system allows us to simulate core-edge-SOL transport without computational boundary in the edge region. The proposed equation system is equivalent to conventional 1D core transport model in the weakly collisional limit and to conventional 2D SOL transport model in the strongly collisional limit.
