 +**Run a reaction network with given nuclear input for:**
 +
 +  - Fixed temperature and density
 +    * Try various temperatures and densities ​
 +    * Try different network sizes
 +    * Swap out a reaction rate with a different version
 +    * Vary initial composition (X, Y, Z or Ye)
 +    * Let evolve until Nuclear Statistical Equilibrium is reached
 +  - Temperature/​density trajectories
 +
 +    * $ T(t) = T(0)\exp{(-t/​\tau)} $ or $\ T(t) = T(0)(1+\frac{t}{n\tau})^{-n} $
 +
 +    * $ [1.+f_{\nu}(T(0))]\rho (t) = \rho (0) [1.+f_{\nu}(T(t))](T(t)/​T(0))^3$
 +
 +
 +    * How do initial conditions affect the resulting nucleosynthesis
 +    * How does the trajectory form affect the results?
