The upload consists of all the MESA-inlist-files, pre-SN models, STELLA input files to generate luminosity and velocity evolution, and also the final STELLA result files. We used MESA version r24.03.1 along with mesasdk version 23.10.1. The abstract of the paper is: 

The upload consists of all the MESA-inlist-files, pre-SN models, STELLA input files to generate luminosity and velocity evolution, and also the final STELLA result files. The abstract of the paper: Supernova (SN) 2024ggi is a nearby Type II SN discovered by ATLAS, showing early flash-ionization features. The pre-explosion images reveal a red supergiant (RSG) progenitor with an initial mass of 10–17 M$_\odot$. In the present work, we perform detailed hydrodynamic modeling to refine and put robust constraints on the progenitor and explosion parameters of SN 2024ggi. Among the progenitor models in our study, the pre-SN properties of the 11 M$_{\odot}$ match the pre-explosion detected progenitor well. However, we find it difficult to completely rule out the 10 M$_{\odot}$ and 12 M$_{\odot}$ models. Thus, we provide a constraint of 11$^{+1}_{-1}$ M$_{\odot}$ on the initial mass of the progenitor. To match the observed bolometric light curve and velocity evolution of SN 2024ggi, the favored model with an initial mass of 11 M$_{\odot}$ has a pre-SN radius of 800 R$_{\odot}$. This model requires an explosion energy of [0.7-0.8]$\times$10$^{51}$ erg, nickel mass of 0.049 M$_{\odot}$, ejecta mass of 9.1 M$_{\odot}$, and an amount of $\sim$ 0.5 M$_{\odot}$ of steady-wind CSM extended up to $\sim1.2\times10^{14}$ cm resulting from an eruptive mass-loss rate of 1.0 M$_{\odot}$ yr$^{-1}$. We also incorporate the accelerated-wind CSM scenario which suggests a mass-loss rate of 1.0$\times10^{-2}$ M$_{\odot}$ yr$^{-1}$ and a CSM mass of $\sim$ 0.7 M$_{\odot}$ extended up to $\sim1.1\times10^{14}$ cm. This mass-loss rate falls within the range constrained observationally.  Additionally, due to the constraint of 11$^{+1}_{-1}$ M$_{\odot}$ on the initial mass, the range of pre-SN radius and ejecta mass would be [690-900] R$_{\odot}$, and [8.2-9.6] M$_{\odot}$, respectively
