**Project:** Nuke Network:: "Simulate the s-process under AGB conditions. Compare to solar system abundances and presolar grains. How does the result depend on initial composition? How good is the waiting point approximation?"

Notes::

**May 30**\\
Big questions:\\
How do we simulate AGB environment in network code?\\
     -abundances of nuclei?
     -density, temp, pressure?
     -mass?\\
What are we going to include in the network?
     -take the entire chart of stable nuclides, and include "padding" on the neutron-rich side

**June 2**\\
Big questions:\\
     -Overall goals: explore how metallicity changes the progression of the s-process
     -Plan of attack:
         - edit sunet & run through the reducereaclib
         - run constant T calculation to validate appropriate network inputs and to debug
         - edit th_input to reflect AGB environment
     -Code additions/modifications:
         - th_input
         - sunet (all stable & some nuetron-rich)
         - eos selection (Bahcall is default - recompile for Helmholtz)
         - match.f90 (only relevant for MPI?)
         - matrix solver (backward Euler?)
     -Most useful visualizations:
         -abundances video?
         -comparison abundances to e.g. [[http://www.as.utexas.edu/~chris/halofield2.jpg|s-process abundance chart]].

**June 3**\\
-Successful implementation of the PARDISO sparse matrix solver into the Xnet code.\\
-[[Reaction network]] run through reaclib & reaction rates obtained.\\

**June 4**\\
-Test runs to check inputs\\
-Started creating presentation\\
-Created visualization of network\\
