We present a single‐explosion model study of the 3C 400.2 supernova remnant (SNR), made with two‐dimensional axisymmetric simulations. The numerical simulations were made with the adaptive grid code yguazú‐a . Several initial scenarios have been tested in order to reproduce the centrally peaked X‐ray emission observed for this remnant. This study reveals that the explosion of the SN inside a pre‐existing stellar wind bubble successfully generates the observed morphology, when thermal conduction is included in the model. The best morphological fit is obtained at an evolution time of 21 000 yr, when the total luminosity is 1.2 × 10 34 erg s −1 .
