Coconut : General relativistic hydrodynamics code with dynamical space-time evolution. The main aim of this numerical code is the study of several astrophysical scenarios in which general relativity can play an important role, namely the collapse of rapidly rotating stellar cores and the evolution of isolated neutron stars. The code has two flavors : CoCoA, the axisymmetric (2D) magnetized version, and CoCoNuT, the 3D non-magnetized version. The CoCoA project was started by Harald Dimmelmeier at the Max-Planck Institute for Astrophysics (Garching bei München, Germany) as part of his PhD thesis. It was extended to 3D (CoCoNuT) in collaboration with Jérôme Novak from the LUTH laboratory at the Observatoire de Paris (Meudon, France). This web page is intended to be a presentation of the numerical code and its scientific results. This code is not of public domain. |

Gyoto : Provide a framework for computing orbits and ray-traced images in General relativity. It consists of a library (libgyoto), utility programs, and a plug-in for the Yorick programing language. Gyoto is known to run under Linux and Mac OS X. Please do tell us if you manage to run Gyoto under a different OS. It should compile and run with moderate effort on most UNIX-like systems |

Lorene : Set of C++ classes to solve various problems arising in numerical relativity, and more generally in computational astrophysics. It provides tools to solve partial differential equations by means of multi-domain spectral methods. Scientific results obtained by means of LORENE are reported here. LORENE classes implement basic structures such as arrays and matrices, but also abstract mathematical objects, such as tensors, and astrophysical objects, such as stars and black holes. Note that, as a research software, LORENE is under perpetual development |
