Studies of identical-particle correlations started with radio astronomy and later with correlations of identical pions in proton-antiproton collisions. These measurements, more generally called femtoscopy, can be used to investigate the space-time dimensions of the region from which the particles are emitted. However the method applied to high energy collisions is sensitive not only to quantum statistics, but also to final state interactions, such as Coulomb interactions when considering charged particles and strong interactions between hadrons. The lack of numerical description of meson-meson correlations motivated the development of a code that solves the Lippmann-Schwinger equation and then obtain the scattered wave functions considering non-local potentials, and afterwards the respective two-particle correlation function. In particular, this procedure is used to investigate the sensitivity of the strong interaction to different source sizes. This numerical solution was applied to the $D^{0}$ mesons ($D^{0}D^{0}$ and $\overline{D}^{0}\overline{D}^{0}$) systems, for which experimental data is yet not available.
