CONCEPT
COsmological N-body CodE in PyThon.
CONCEPT (COsmological N-body CodE in PyThon) is a free and open-source simulation code for cosmological structure formation. The code should run on any Linux system, from massively parallel computer clusters to laptops. The code is written almost exclusively in Python, but achieves C-like performance through code transformation using a custom transpiler/optimizer and Cython.
CONCEPT is capable of simulating matter particles evolving under self-gravity in an expanding background. It has multiple gravitational solvers to choose from, and has adaptive time integration built in. In addition to particles, the code is further able to evolve fluids at various levels of non-linearity, providing the means for the inclusion of more exotic species such as massive neutrinos.
