Longitudinal decorrelation from CLVisc for PbPb 2760 GeV and AuAu 200 GeV relativistic heavy ion collisions

Relativistic fluid dynamic simulation code CLVisc has been used to describe the de-correlation of event planes and anisotropic flows in high energy heavy ion collisions. The data are from viscous hydro simulations with shear viscosity eta/s=0.16 and AMPT initial condition. The CLVisc is a (3+1)D viscous hydrodynamic program parallelized on GPU using OpenCL. It is publicly available from here: https://gitlab.com/snowhitiger/PyViscThe description of the code and the physical definitions of the data is shown in details in the following paper,http://inspirehep.net/record/1654800
