mpgrafic 0.3.19                                    August 2020                                       MPGRAFIC(1)

       mpgrafic  produces  initial conditions files for N-body simulations of cosmological large-scale structure
       formation. It is a free-licensed, MPI-parallelised,  rewritten  version  of  Ed  Bertschinger's  grafic-1
       program,  producing  output  files  in  the  grafic  format. It includes options for an Eisenstein and Hu
       baryonic wiggles power spectrum, for using a low-resolution map for large-scale modes in  the  spirit  of
       grafic-2,  and  together  with  constrfield,  can  be used for generating constrained initial conditions.
       Details are given in Prunet et al (2008) http://cdsads.u-strasbg.fr/abs/2008ApJS..178..179P.
