Hint
The lipid tails are in the center, and form a core with low $\Delta \rho$. The heads form a shell with higher $\Delta \rho$. So a micelle can be represented by a spherical core-shell particle.In most cases, micelles are not fully spherical, so they should be simulated as a core-shell ellipsoid.
Moreover, one has to take polydispersity into account (see the Polydispersity tutorial). For this tutorial we will, however, stay with the simplest example of a spherical core-shell particle.
