Abstract

Self-consistent field theory (SCFT) is one of the most widely used tools to study the equilibrium phase behavior of block polymers. We have extended an existing version of the Anderson-mixing iteration scheme to solve the highly nonlinear SCFT equations while simultaneously optimizing the unit-cell dimensions. This improved scheme substantially increases the computational efficiency compared to existing schemes.
