What is Simantics?

Open platform for modelling and simulationDeveloped at VTT since 2006Application development platformIntegration solution for modelling and simulationSemantic graph based representation of dataLicenced under Eclipse Public Licence

GoalsReusable components for modeling and simulation infrastructure (less focus on solver technology)Multi-disciplinary, multi-level simulation and modelingSupports the whole life cycle of the facility or productDistributed simulationModel integrationSolver integrationTeam work

Ontology Language – Layer0Formal specification at http://dev.simantics.org/images/c/c8/Layer0.pdf

Used graphical notation is described at https://www.simantics.org/wiki/index.php/Graphical_ontology_notation

Why Ontologies?

Flexibility: Quite different data models of different simulators and design systems expressed using the same languageModel validation

Capturing knowledge of experienced modellers (rules)Semantic queriesModel transformationsModel annotations

Ontology challenges

Performance issuesQuite complex low level API’s

Need for experienced and skillful programmers in the coreOntology versioning

Model migration from one ontology version to anotherCode plugins that would handle several ontology versions
