This trail section offers a very quick introduction to UML Activities and Actions only. Please note that SysML® introduces many useful additions to Activity modelling as covered later in the main SysML trail.
This trail section is currently mostly just annotated diagrams only - with no additional text explanations except for linked Notes and Snippet spec extracts
This tutorial trail section includes some simulation example micro-videos
There is an entire separate trail on Activities (and StateMachines) with many simulation mini videos here:
TRAIL: SysMLv1/UML: Cameo Simulation Toolkit® (Magic Model Analyst®): Some basics for beginners and some more advanced cases [with mini videos]

If you are already a "UML ninja" by all means skip to the SysML starting point:

TIP: SysMLv1/UML: Cameo Simulation Toolkit: HOWTO convert an fUML ReadLine CLI String to a Boolean for cleaner DecisionNode tests against a LiteralBoolean [true] guard.
TIP/GOTCHA: SysMLv1/fUML: Cameo Simulation Toolkit: If you have a ControlFlow loop with a DecisionNode test you MUST have a MergeNode for the continuation path ControlFlow (typically entered also from an InitialNode or other loop starting point).
TIP/GOTCHA: SysMLv1/UML: Cameo Simulation Toolkit: If you use a «decisionInputFlow» to a DecisionNode you MUST also have a ControlFlow to the DecisionNode; if you don't use an explicit «decisionInputFlow» you don't need the "extra" ControlFlow
MagicDraw/Cameo: UML/SysML: TIP: Activity Diagrams: Learn how to use the Refactor > Extract feature to divide-and-conquer and identify cleaner flow and logic. Get control of those crossed wires!
Webel: MagicDraw/Cameo: UML/SysML: TIP: Activity Diagrams, StateMachine Diagrams, and port-based IBDs: Keep it loose initially with oblique (no break) paths, then square it up with rectangular paths at the very end
UML/SysML: TIP: Using Cameo Simulation Toolkit will strengthen your use of Activity Diagrams even when they are "just" analysis diagrams
