Computational fluid simulation in astrophysics deal with unique challenges not present in classical computational fluid simulations. Among these challenges is the need to maintain two copies of the state variables: conserved variables that can be evolved in time using the evolution equations and primitive variables required to close the system of evolution equations via an equation of state. At timestep and for each point in space the simulation code solves non-linear equation to convert from one set to the
other. This project aim to improve the treatment of the primitive variable recovery in simulations using the Einstein Toolkit. Specifically we will implement the methods described in Tchekhovskoy et al, 2007 (section 3.6) de-averaging the conserved variables before primitive recovery and study the effect this has on simulations
