A new cosmological multidimensional hydrodynamic and N-body code based on an adaptive mesh refinement scheme is described and tested. The hydro part is based on modern high-resolution shock-capturing techniques, whereas the N-body approach is based on the particle mesh method. The code has been specifically designed for cosmological applications. Tests including shocks, strong gradients and gravity have been considered. A cosmological test based on the Santa Barbara cluster is also presented. The usefulness of the code is discussed. In particular, this powerful tool is expected to be appropriate to describe the evolution of the hot gas component located inside asymmetric cosmological structures.
