Is swift a universe simulation code language

Answer 1

SWIFT is a hydrodynamics and gravity code for astrophysics and cosmology. ... We use SWIFT to run simulations of astrophysical objects, such as planets, galaxies, or even the whole universe. We do this to test theories about what the universe is made of and how it evolved from the Big Bang up to the present day!
