# inhomog(1)

biscale kinematical backreaction analytical evolution

## NAME

inhomog - biscale kinematical backreaction analytical evolution

## SYNOPSIS

**inhomog** \[*OPTION*...\]

## DESCRIPTION

biscale kinematical backreaction analytical evolution

The inhomog library provides Raychaudhuri integration of cosmological domain-wise average scale factor evolution using an analytical formula for kinematical backreaction Q\_D evolution. The inhomog main program illustrates biscale examples. The library routine lib/Omega\_D\_precalc.c is callable by RAMSES using RAMSES-SCALAV (see Roukema 2018 A&A 610, A51, arXiv:1706.06179).
