Anisotropy function of kinetic coefficient for phase-field simulations: Reproduction of kinetic Wulff shape with arbitrary face angles

► We propose new anisotropy function of kinetic coefficient for phase-field simulations. ► The new function allows us to simulate crystal growth with flat facets. ► The growth form may have arbitrary number of facets and face angles (high flexibility). ► We introduce new parameter to check validity of the anisotropy function. ► Using the function, we can simulate crystal growth to more general shapes.
