DESCRIPTION:High-resolution magnetohydrodynamic (MHD) simulations rely on 
 Adaptive Mesh Refinement (AMR) to resolve localized features efficiently\,
  yet maintaining the magnetic field divergence constraint across refinemen
 t boundaries remains non-trivial. In this talk\, I will present an overvie
 w of general AMR strategies before describing the implementation being dev
 eloped in gPLUTO with particular emphasis on staggered grids. On these gri
 ds\, magnetic fields are stored on cell faces and electric fields on cell 
 edges. I will discuss the resulting challenges in communication and synchr
 onization across refinement levels\, compare divergence cleaning with cons
 trained transport\, and explain the role of flux and electromotive-force c
 orrections at coarse–fine interfaces to prevent the development of magne
 tic monopoles at AMR boundaries. The talk will conclude with the current s
 tatus of the implementation and ongoing validation.
