The formation and evolution of a low mass galaxy in the gravitational field of a massive disk galaxy (like the Milky Way) has been studied. Numerical simulations of complex gas-dynamic flows are based on our own variant of the Chemo-Dynamical Smoothed Particle Hydrodynamical (\bf CD-SPH) approach, which incorporates star formation. The dynamics of the dark matter was treated as a standard N-body problem. It is shown that the satellite galaxy effectively looses its dark matter component due to the strong tidal influence of the massive galaxy, while the gas, owing to its strong dissipative nature, forms an almost dark-matter-free dwarf galaxy.
