Adaptive Smoothed Particle Hydrodynamics (ASPH) - a new and improved version of the well-known SPH method for numerical gas dynamics - has been developed for the study of galaxy and large-scale structure formation and the evolution of the intergalactic medium. This ASPH method replaces the isotropic smoothing algorithm of SPH with anisotropic smoothing involving ellipsoidal kernels whose axes evolve automatically to follow the mean particle spacing as it varies in time, space, and direction around each particle. Application of this new method to simulate cosmic structure formation in 3D will be described.
