We propose a highly coarse-grained, self-consistent field (SCF) theory for simulations of symmetric diblock copolymers, based on the soil dumbbell model. We apply the standard derivation method of the SCF model to the soft dumbbell model, and derive the set of self-consistent equations. We perform the SCF simulations In one dimension, based on the derived model, and show that the SCF model can reproduce microphase separation structures properly. We theoretically consider the properties of the model and discuss possible applications. [ABSTRACT FROM AUTHOR]
