In this page I will make available some codes that I have written. You can freely use and modify them.
Code to compute the density power spectrum in cosmological simulations. It uses MPI and FFTW-2.15. The code is referenced in ASCL:1403.015.
The following codes are available upon request.
Computes the density field (using NGP, CIC, or TSC scheme), and smooth it with a Gaussian kernel. Uses FFTW, MPI-parallel.
Short program to convert from GOTPM to Gadget format.
