Model Factual CAE Knowledge

• Philosophie: Study basic categories of being

• Computer science: Knowledge representation

• Compatibility through shared

Upper Ontologies

• Well suited for

data integration

Data ontology

What is represented by the

data?

• Information content entity

How is the data represented?

• Information structure entity

15

June 7th-9th | Seattle, WA2016 NAFEMS Americas Conferencenafems.org/americas

Algorithm ontology

• Draws on existing standards,

e.g. OpenAPI model

• Based on data ontology

• Integrates different software

modules and services

• Alternative representation

by YAML/JSON

16

June 7th-9th | Seattle, WA2016 NAFEMS Americas Conferencenafems.org/americas

Simulation ontology

• Representation of simulationknowledge

• Models, boundaryconditions, solvers…

• Based on existing work, e.g. HuPSON ontology, Step AP 209

• Workflow representationand simulationautomatization

17

June 7th-9th | Seattle, WA2016 NAFEMS Americas Conferencenafems.org/americas

Current work: Learn from experience

• Semantic database ofsimulation data

• Use machine learning toextract knowledge

• Deep learning for shapeunderstanding

• Enables: BC transfer, automate defeaturing, meshing etc.
