We have added the effect of the energy injection sustained by a magnetar in the hydrodynamic simulations of supernovae (SNe) by \cite{2011B}.The variation of the properties of the ejecta and the magnetar introduce changes in the light curve (rising timescale, maximum luminosity, width). We present the most important features of the morphologies found for the light curves of a synthetic population of SNe with and without hydrogen.As part of the work in progress, we are looking for the parameters to explain the observational data of SN2018cow which is a bright SN (Lmax>1044 ergs−1) that, unlike the general case for superluminous SNe, was located very close (60 Mpc). It has drawn attention given the rapid evolution of its light curve. It has been the subject of many multi-frequency campaigns and several theoretical frames were debated in order to explain it.The idea of a magnetar is not new in this case, but hydrodynamic calculus is, as an improvement to more simplifying proposals presented in the literature.
