The proposed work builds on this success by aiming to (i) generalize the method for solving the Boltzmann exactly for flow patterns of different symmetry that can be applied at lower heavy-ion collision energies orto supernova explosions, (ii) generalize the previously found exact solution from a relaxation time collision term to a fully non-linear Boltzmann collision term, (iii) include external fields into the solution of the Boltzmann equation and explore their effects on the thermalization process, and (iv) develop a numerical implementation for heavy-ion collisions of viscous anisotropic hydrodynamics which is based on the most accurate hydrodynamic approximation scheme revealed in our tests against the exact solution found in our previous project. Expected results from this project include a fully functional 3-dimensional viscous anisotropic hydrodynamic code for phenomenological analysis of data collected in relativistic heavy-ion collision experiments, an improved understanding of the approach to local equilibrium in the early stage of the collision and its representation using hydrodynamics, and fundamental insights into the applicability of hydrodynamics in a broad range of physical environments involving rapidly evolving plasmas.
