DESCRIPTION:  High-resolution magnetohydrodynamic (MHD) simulations rely o
 n Adaptive Mesh Refinement (AMR) to resolve localized features efficiently
 \, yet maintaining the magnetic field divergence constraint across refinem
 ent boundaries remains non-trivial. In this talk\, I will present an overv
 iew of general AMR strategies before describing the implementation being d
 eveloped in gPLUTO with particular emphasis on staggered grids. On these g
 rids\, magnetic fields are stored on cell faces and electric fields on cel
 l edges. I will discuss the resulting challenges in communication and sync
 hronization across refinement levels\, compare divergence cleaning with co
 nstrained transport\, and explain the role of flux and electromotive-force
  corrections at coarse–fine interfaces to prevent the development of mag
 netic monopoles at AMR boundaries. The talk will conclude with the current
  status of the implementation and ongoing validation.
