Continuous Domain

The Continuous Domain is a redesign of the Continuous Time (CT) domain with a rigorous semantics documented in the following papers:

The domain models systems with continuous dynamics, including for example analog circuits and mechanical systems, but also cleanly supports discrete events, modal behaviors, and signals that mix continuous-time behaviors with discrete events. Models for continuous dynamics are equivalent to linear or nonlinear integral equations. A sophisticated numerical solver for these equations is integrated with the director. The clean semantics of the Continuous domain enables its integration in hierarchical heterogeneous models that use the Synchronous/Reactive (SR) and Discrete Event (DE) domains. Arbitrary hierarchical mixtures of these domains are supported, although if SR is at the top level, then the period parameter of the director must be used so that time advances. Domain interactions are documented in the following paper:
