k-evolution (arXiv:1910.01104) is based on gevolution N-body code (Adamek J., Daverio D., Durrer R., and Kunz M., Nature Phys. 12, 346 (2016), arXiv: 1604.06065).
k-essene based the EFT framework is added into the gevolution The free parameters to be chosen are w (the equation of state for dark energy) and c_s^2 (the speed of sound squared).
Before compilation, make sure that all required external libraries are installed:
- LATfield2 version 1.1
- FFTW version 3
- GNU Scientific Library (GSL) including CBLAS
- HDF5
Make sure that the include paths are set properly, or add them to the makefile. Also check the compiler settings in the makefile. The code is compiled by typing:
make
A typical command to run a simulation looks like this:
mpirun -np 16 ./gevolution -n 4 -m 4 -s settings.ini
