NEWS: New detailed Systems Modeling Language v1 (SysML®) tutorial trails with examples of slides from the Webel course: TRAIL: Webel's ultimate guide to Systems Modeling Language (v1) with MagicDraw/Cameo
NEWS: New detailed Systems Modeling Language v1 (SysML®) tutorial: TRAIL: The SysML-1.6 Hybrid SUV sample and specification diagrams in MagicDraw/Cameo (with annotations) [UNDERGOING UPDATE to SysML1.7]
This Webel zone is dedicated to the OMG's Systems Modeling Language v1 (SysML®) extension (dialect) of the Unified Modeling Language (UML®):

Dr Darren of Webel IT Australia is recognised as a leader in graphical software and systems engineering technologies and was actively involved in the specification process for OMG SysML® (v1). He was formerly Expert Consultant for Science & Engineering for development of the MagicDraw SysML Plugin for MagicDraw® — now bundled as Magic Cyber-Systems Engineer ® (Cameo Systems Modeler®) — and has applied SysML to a wide-range of real-world projects from many domains such as modelling of scientific instruments, building and construction projects, digital twins, green rating schemes, electronics, physics models, and design and patenting of inventions.

Please note that the Webel Best Practice notes for both UML® and SysML® and for the MagicDraw and Cameo tools are now combined here.
You DO NOT have to wait for SysMLv2 to do Model-Based Systems Engineering with SysML! You can do MOST of what you need to do with SysMLv1.6/1.7 and you WILL be able to migrate models to SysMLv2 once tool support matures. Start your SysML models NOW!

SysMLv1 vs SysMLv2
Representing the SysMLv1 Block and SysMLv2 Part Def in Mathematica requires classes and object orientation (OO)
OMG Systems Modeling Language (SysML) 1.7beta1
Webel: SysML/UML: Some example diagrams show extremely fine-grained and trivial examples purely for educational and capability demonstration purposes (not as practical recommendations for real-world projects). You can sometimes just use code in SysML.
Webel: SysML4Mathematica: POLICY: Handle flow sign changes via a single negative (not duplicated and "adjusted" algebra). This strategy may come at a very slight performance cost (for benefit of more robustness).
Webel: SysML4Mathematica: SysML Activities and SysML Activity Diagrams CAN represent some functional programming paradigms (sort of). You can type Parameters by encapsulations of functions and pass them to/from InputPins/OutputPins of Actions.
Webel: SysML4Mathematica: TIP: Representing Mathematica Paclets and their inter-dependencies as SysML Packages modelled in SysML Package Diagrams can really help you organise your Wolfram Language code on complex projects!
Webel: SysML4Mathematica: TIP: Representing Mathematica functions as SysML ConstraintBlocks modelled in Block Definition Diagram (BDD) overviews can really help you organise and document your Wolfram Language code on complex projects!
Webel: SysML4Mathematica: TIP: Representing Mathematica functions as SysML ConstraintBlocks modelled in SysML Parametric Diagrams and as Activities in SysML Activity Diagrams is super for analysing the dependencies between functions and their arguments!
Webel: SysML4Mathematica: TIP: Exported SysML Diagrams can be embedded in Mathematica Notebooks!
Webel: SysML4Mathematica: Convention: A custom SysML ValueType 'Quantity' extends a custom ValueType '_' (representing a Mathematica '_' Blank). It DOES NOT also extend the SysML Real!
Webel: SysML4Mathematica: Convention: A Mathematica Blank '_' (which pattern-matches any Expression) is represented by a custom SysML ValueType '_'
SysML4Mathematica: Example: Block Definition Diagram overview of ConstraintBlocks, their parameters, and ConstraintBlock usages representing lower-level Webel Psy library Psychrometrics functions and CoolProp wrapper usages
The Webel SysML4Mathematica recipe for modelling Wolfram Language code in Systems Modeling Language (SysML) for Model-Based Systems Engineering
SysML/UML: MagicDraw/Cameo: GOTCHA: Connecting a typed OutputPin to an untyped (UNSPECIFIED) InputPin with an ObjectFlow changes the type of the InputPin
Webel: SysML4Mathematica: Convention: A '$E' in a function name indicates that all parameters (arguments and return) are Mathematica '_' expressions. However, when representing such functions as Activities they may end up getting strongly typed in tools!
Webel: SysML4Mathematica: When modelling the main logic flow of Mathematica code with Activity Diagrams it isn't necessary to model every Mathematica construct. Placeholder Actions, OpaqueActions , and OpaqueBehaviors (as CallBehaviorActions) may be used.
