Description

We present a numerical code for modeling relativistic heavy ion collisions, ECHO-QGP. The code includes relativistic hydrodynamics with dissipative terms and implements Israel-Stewart theory in 3+1 D. Initial conditions are provided through an implementation of the Glauber model (both Optical and Monte Carlo), while freezeout and particle generation is based on the Cooper-Frye prescription. ECHO-QGP features dynamical metric tensor in a GR framework for ideal hydro and it can work in Bjorken and cartesian frames for the dissipative case. The code shows remarkable stability and accuracy with the combination of a conservative (shock-capturing) approach with the high-order methods. ECHO-QGP is able to reproduce several known solutions of ideal and dissipative hydrodynamics including the lately proposed Gubser test. Ref. L. Del Zanna, V. Chandra, G. Inghirami, V. Rolando, A.
