DESCRIPTION:MUSIC is a fully compressible\, time-implicit code
  for stellar hydrodynamics\, designed to study pro
 cesses such as convection and waves in stellar and
  planetary interiors. The code is written in Fortr
 an 2008\, and coupled to the C++ Trilinos library.
  Recent science goals have called for major evolut
 ions of the code\, and of the associated ecosystem
  of tools. In this talk\, I will present our recen
 t efforts to make the MUSIC code more robust\, mor
 e expressive\, and easier to maintain and extend.\
 n\n\nI will discuss how our ongoing rework of the 
 code\, driven by science requirements and guided b
 y key principles in software design\, has made it 
 possible to implement new physics\, while reducing
  complexity and improving performance. I will focu
 s mainly on recent architectural developments in t
 he code. In particular\, I will show how the trans
 ition to object-oriented programming techniques an
 d lazy evaluation of the physical equations helped
  make the code more declarative and decoupled.\n\n
