Title: Upgrading Smoothed Particle Hydrodynamics Calculations

In the last years there has been a change of paradigm within the SPH calculations. What was considered as 'standard' in SPH has been renewed by a set of recent formalisms that have helped to overcome various long-lasting inherent problems of this numerical technique. These new additions include, among others, the use of new kernels resistant against pairing instability, and more accurate gradient calculation via an integral approach. In this talk I will focus in how these simple changes can substantially improve our SPH calculations at almost no cost.
