The numerical resolution is based on the Galerkin finite element discretization of the collective space and the Crank–Nicolson scheme for time integration. The TDGCM solver is implemented entirely in C++. Several additional tools written in C++, Python or bash scripting language are also included for con... Title of program: FELIX-1.0 Catalogue Id: AEYZ_v1_0 Nature of problem Nuclear fission is a relatively slow process compared to the typical timescale of the intrinsic motion of the nucleons. In the adiabatic approximation, it can be described as a large amplitude collective motion driven by only a few collective degrees of freedom. In the time-dependent generator coordinate method (TDGCM), the nuclear wave-function is thus described as a time-dependent, linear superposition of basis functions in this collective space. Further assuming a Gaussian overlap approximati ... Versions of this program held in the CPC repository in Mendeley Data AEYZ_v1_0; FELIX-1.0; 10.1016/j.cpc.2015.11.013
