Description

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract We describe the software package FELIX that solves the equations of the time-dependent generator coordinate method (TDGCM) in N -dimensions ( N ≥ 1 ) under the Gaussian overlap approximation. 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
