The S-PLUS Fornax project (S+FP) aims at studying the Fornax galaxy cluster using photometricdata in 12 optical bands. As a part of that project, this work presents the first steps towards a comprehensive comparison between the properties of simulated galaxy clusters and the observed characteristics of Fornax. Our final goal is proposing possible formation scenarios for the Fornax cluster. Specifically, we present the analysis of Fornax-like candidates extracted from state-of-the-art cosmological numerical simulations (e.g. illustris-tng and eagle simulations), selecting them according to observed features in the Fornax cluster. The spectral energy distribution of galaxies in our simulated clusters were computed and used to estimate photometric parameters that can be directly compared with observations in the 12 optical bands of S-PLUS. Also, data cubes with surface brightnesses in those bands and synthetic images of the simulated galaxies were generated, in order to carry outan initial comparison with Fornax galaxies.
