Equilibrium shape (magenta lines) and final precipitate shapes in the simulation domain (black lines) for the cubic anisotropy, Eq. (9), with \(F_{\alpha \beta }=0.45\) for the regularized classical model, Eq. (16), in the top row, and for the regularized natural model, Eq. (17), in the bottom row. In the left, in the middle and in the right columns, the coefficient B in Eqs. (20) and (21) is 0.06, 0.3, and 0.6, respectively
