DESCRIPTION:In many astrophysical MHD contexts\, the computati
 onal feasibility of covering all the scales of int
 erest (from the dominion size down to the dissipat
 ive scales) is and will be many orders of magnitud
 e away from what would be ideally needed. Large ed
 dy simulations are used to partially compensate su
 ch lack of numerical resolution\, introducing sub-
 grid-scale models. I present our compressible MHD 
 extension of the so-called gradient model\, that c
 an be implemented for any problem\, equation of st
 ate\, in relativistic and non-relativistic cases. 
 I show the breakthrough results of our main applic
 ation so far\, the magnetic amplification during m
 ergers\, and we can all discuss possible direct ap
 plications to planetary dynamo codes.
