SysML v2 Examples

Open-source SysML v2 models maintained by Elan8 — from compact learning examples to engineering-grade reference architectures. These repositories are MIT-licensed and designed for learning, teaching, and tooling validation. Clone a repo, open the models in a SysML v2-capable editor such as Spec42, or browse the source on GitHub. For specifications and community links beyond Elan8 models, see SysML v2 resources.

Learning

elan8/sysml-examples

View on GitHub

Short, readable SysML v2 text models for learning, teaching, and quick experimentation with tools and editors.

  • office — smallest intro model for orientation
  • timer — best end-to-end reference in the collection
  • intersection — behavior-focused traffic light controller
  • drone — larger multi-subsystem system model
  • webshop — software architecture-focused example

Good for: Students, educators, and teams trying SysML v2 tooling on small models before larger projects.

Autonomous Floor Cleaning Robot

Reference model

elan8/sysml-robot-vacuum-cleaner

View on GitHub

Engineering-grade SysML v2 model for an autonomous floor-cleaning robot — larger than a toy example, still readable end to end.

  • Requirements-to-architecture-to-verification traceability
  • Functional and physical decomposition with explicit allocations
  • Safety analysis, trade studies, verification cases, and stakeholder views
  • Implementation-facing interface control for harnesses, firmware, and MCU deployment
  • Validated with Spec42 in CI

Good for: Systems engineers and tool builders who need a realistic MBSE corpus with full lifecycle coverage.

Astronomy Reference

Scientific domain

elan8/sysml-v2-astronomy-reference

View on GitHub

Open SysML v2 reference model for astronomy, starting with a compact Solar System and structured for long-term extension.

  • Celestial body taxonomy, orbital mechanics, and reference frames
  • Requirements, constraints, calculations, analyses, and views
  • Representative physical and orbital values with provenance patterns
  • Python extractor and Three.js Keplerian orrery simulator showcase
  • Demonstrates scientific-domain modeling beyond typical product engineering

Good for: Engineers, educators, and astronomy enthusiasts exploring SysML v2 in scientific domains.
