Before using any of these thermonuclear 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 the JINA lectures on reaction networks.

There is a certain irremovable complexity associated with stiff systems of ordinary differential equations when the right hand side is a complicated function, the Jacobian matrix is sparse, and you want to do a high quality integration. The routines below use an analytical Jacobian, a variable-order Bader-Deuflhard integration method, and MA28 sparse linear algebra. These reaction networks are not toys.

In this version, the reaction network and thermodynamics are integrated simultaneously. That is, they are fully coupled. At present, one-step, hydrostatic, adiabatic expansion, self-heating at constant density, self-heating through constant pressure, detonation, and arbitrary thermodynamic histories are supported.

If you want to put these reaction networks in a hydrodynamics code and/or you want the networks to execute as efficiently as possible, send a message to me.
