MZK Program for Solving Stiff Systems in Nuclide Kinetics Problems

The MZK program was developed to solve stiff systems based on ultra-precise solvers in the SADEL library, where AL-stable implicit methods with variable integration steps and computational algorithms with guaranteed accuracy are implemented taking rounding errors into account. MZK implements a computational algorithm with heightened digit capacity and reliability control of solutions at each step of numerical integration, so that MZK can be used to obtain reference values in high-precision calculations of nuclide kinetics problems.
