Abstract:

A computer system for the automated numerical integration of chemical type equations has been developed. The manual describes the use of the system, its input and output, and the incorporation of the generated FORTRAN program in an user program. The developed ARIS system has the following features which are essential for the successful use of such a system 1 It is complete which means the input to the system is sufficient to generate a complete chemistry program including error printouts. The generated program is efficient vectorizable and simple to incorporate in the user program 2 The reaction are to be given in a physical form A B ... C D ...with reaction energies E,C, ... The programming for initiation, back substitution, rate coefficients, conversion factors and additional source terms is easy. The generated FORTRAN is comprehensible and 3 The ARIS system provides integration schemes suited for stiff equations with special features for asymptotic behavior. Author.
