Numerical simulations of galaxy clusters including two species -- baryonicgas and dark matter particles --are presented. Cold Dark Matter spectrum,Gaussian statistics and flat universe are assumed. The dark matter component isevolved numerically by means of a standard particle mesh method. The evolutionof the baryonic component has been studied numerically by using amultidimensional (3D) hydrodynamical code based on modern high resolution shockcapturing techniques. These techniques are specially designed for treatingaccurately complex flows in which shocks appear and interact. With thispicture, the role of shock waves in the formation and evolution of rich galaxyclusters is analyzed. Our results display two well differenced morphologies ofthe shocked baryonic matter: filamentary at early epochs and quasi-spherical atlow redshifts.Comment: 28 pages, LaTex with aasms4.sty, 12 postscript figures, tared,gziped and uuencoded.
