| + | - Make sure everyone got the pre-test done and correct. | ||
| + | - Re-run the pre-test, reducing the temperature in the thermodynamic file | ||
| + | * Find the minimum temperatures at which silicon burning, oxygen burning and carbon burning occur. | ||
| + | - Grab a new (larger, 150 species) sunet_sn150.txt from the document server. | ||
| + | * Rename sunet_150.txt to sunet | ||
| + | * Build a new Data directory from REACLIB | ||
| + | * Create a new initial abundance file (matching the composition in the pretest) | ||
| + | * Run same test problem with new network | ||
| + | * Compare results to pre-test. | ||
| + | * Compare timing of pre-test to new problem. | ||
| + | |||
| + | |||
| + | Additional possibilities: | ||
| + | |||
| + | **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? | ||
