Data for: Numerical optimization of a multiphysics calculation scheme based on partial convergence

-FixedPointPerformances and fxdpnt_perf are respectively the text and the pickle format (Python) of the performance of fixed-point iteration schemes with different partial convergence settings and different relaxation factors. -Files of the type keff-*-100-40 are the results of the power iteration process for different relaxation factors for one partial convergence setting (limits: 100 neutronic iterations and 40 thermal-hydraulic iterations). They aim at showing the bifurcations that may appear consequently to small perturbation of the relaxation factor.
