I will present the recent development of multi-dimensional stellar structure models based on a new fully compressible hydrodynamicsl time implicit code, the MUSIC code, devoted to stellar and planetary interiors. I will discuss the main challenges in the computations of multi-dimensional stellar structures and some of the advantages of our approach with MUSIC for the study of stellar fluid dynamics problems. MUSIC is interfaced with stellar evolution codes, which provide initial 1D stellar structures for any type of star and allow exploration of a wide range of stellar phases and masses. I will present our study of overshooting in solar like stars stars. I will show the success of our approach with MUSIC within the context of lithium depletion in the Sun and in solar-like stars. A major motivation for these studies is to derive new prescriptions to be implemented in stellar evolution codes and improve stellar evolution models that are widely used in stellar and galactic astrophysics.
