adevs: Adevs (A Discrete EVent System simulator) is a C++ library for constructing discrete event simulations based on the Parallel DEVS and Dynamic DEVS (dynDEVS) formalisms. DEVS has been applied to the study of social systems, ecological systems, computer networks and computer architecture, military systems at the tactical and theater levels, and in many other areas. Recent advances in quantized approximations of continuous systems suggest promising computational techniques for high performance scientific computing (e.g. in the field of computational fluid dynamics)
