mpgrafic - 0.3.18-1 main

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
