The article discusses the problem of verification and validation of engineering software when solving problems of nonlinear dynamics. The problems of validation and verification are shown on the example of dynamic chaos systems. The results of testing systems are presented. It is shown that in general when solving problems of nonlinear dynamics the characteristics of the developed engineering software are of critical importance. It is also indicated that neglecting this fact leads to irreversible negative consequences, ultimately resulting in the decay of the dynamics of a nonlinear system as well as in the decay of its orbits. The influence of the hardware and a number of aspects of the system and software implementation of the verification and validation systems under study is also shown. The article demonstrates modern approaches to the development of the studied software systems. It is shown that a high-quality software product suggests division into subsystems and stages.
