Data and Plotting Codes for Four Benchmark Cases of a Nuclear–Thermal Coupled Solver

The four cases cover heat transfer, neutron diffusion, surrogate-model evaluation, and coupled neutronic–thermal analysis. The dataset includes numerical, physics-informed neural network (PINN), and DeepONet results used to generate and compare the figures presented in the associated study.

Selected trained model parameters and supporting input data required by the plotting codes are also provided where necessary. The files are organized into four case-specific folders. Generated figure files and unrelated training intermediates are not included.
