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 high-quality time integration. The tools below use an analytical Jacobian, a variable-order Bader-Deuflhard integration method, and MA28 sparse linear algebra. The reaction network and thermodynamics are integrated simultaneously. That is, they are fully coupled. Hydrostatic, one-step, adiabatic expansion, self-heating at constant density, self-heating 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.
