Before using these reaction networks you should probably glance at my method of madness, Raph Hix's & Brad Meyer's excellent article, Brad Meyer's annual review article, George Wallerstein's review of modern physics article, and this National Nuclear Physics Summer School lectures on reaction networks. There is a certain irremovable complexity associated with stiff systems of ordinary differential equations $$ \dot {{\bf y}} = {\bf f} \ ({\bf y}) \label{eq1} \tag{1} $$ when the right hand side is a complicated function, the Jacobian matrix $\tilde{{\bf J}}$ is sparse, and one wants a highquality time integration. The tools below use an analytical Jacobian, a variableorder BaderDeuflhard integration method, and MA28 sparse linear algebra. The reaction network and thermodynamics are integrated simultaneously. That is, they are fully coupled. Hydrostatic, onestep, adiabatic expansion, selfheating at constant density, selfheating through constant pressure, and arbitrary thermodynamic histories are currently supported. These reaction networks are a snapshot of my current research efforts. If you want to put these reaction networks in a stellar evolution or hydrodynamics software instrument, and/or you want the networks to execute as efficiently as possible, feel free to contact me.
