Q: What types of simulation, execution, and calculation are available for SysML with MagicDraw/Cameo?

Keywords

Keywords

There are a number of ways of simulating and executing various aspects of Systems Modeling Language (SysML®), and they are not just novelties! They also really help your models become more robust, logical, and organised.

There is "internal" tool simulation of Activities and StateMachines based on fUML (or variations of it).
