Recently we showed that an expressive class of mathemat-ical equations can be automatically translated into simula-tion codes. Focusing on the expressivity of equations oncontinuous functions, this work considered only minimal in-teraction with discrete behaviors and only a static numberof statically connected components. However, the interac-tion between continuous and hybrid components in manycyber physical domains is highly coupled, and such systemsare often highly dynamic in both respects. This paper givesan overview of a proposed core language for capturing ex-ecutable hybrid models of highly dynamic cyber physicalsystems.
