We present a numerical simulation carried out in order to explain the complex morphology of the supernova remnant (SNR) 3C 400.2. Numerical simulations were done employing the new yguazú-a code (Raga et al. 2000). In the radio continuum, this remnant seems to be formed by two shells, which are partially overlapping ([CITE]). Taking into account observational evidence such as a previous HI study ([CITE]), we find that an adequate model for describing the morphology of the SNR 3C 400.2 is obtained by assuming that a single supernova (SN) explosion took place in a dense medium and close to an interface separating this medium from a lower density region. Besides, we also present a new deeper CCD Hα image mosaic of the north-west region of this SNR, which is composed of three single images. From the numerical results, we generated Hα emission maps, obtaining a good agreement with the observations.
