STAR-CCM+ in your workflow Introduction: Sample workflow Conceptual Conceptual Results Results Manufacturing Manufacturing, CAD Simulation Design Review design analysis etc. Real simulation workflows involve many other components: y p • – Optimization loops – Validation/verification – PLM technology – Co-simulation The goal of the pre/post-processing group is to position The goal of the pre/post-processing group is to position • • STAR-CCM+ as a usable, robust, and efficient simulation tool in any workflow STAR Konferenz Deutschland 2009, 9-10 Nov. 2009 3
STAR-CCM+ in your workflow Introduction How do we help position STAR-CCM+ in your workflow? • – By accepting input data from different sources, By accepting input data from different sources – By providing tools to organize and prepare data, – By healing poor-quality CAD through a robust, automated surface wrapping procedure, – By allowing detailed interrogation and reporting of solution data, data, – By providing a powerful, highly customizable scripting API for fully automated analysis STAR Konferenz Deutschland 2009, 9-10 Nov. 2009 4

Advanced physics settings are maintained.
Where are you starting? CAD Data: Direct CAD import STAR-CCM+ supports • direct import of native and neutral CAD formats from all major CAD packages. Imported CAD data can • then be used for accurate, “on-surface” mesh generation. h ti Continually working with • our CAD partners to i improve quality and lit d robustness of CAD import STAR Konferenz Deutschland 2009, 9-10 Nov. 2009 8
Where are you starting? PLM Data: Direct PLM import Work is ongoing to support a tight • integration of STAR-CCM+ into a Medina XML PLM-enabled workflow. JT Open Import of model data from PLM can PLM XML • include: Others? Model Data – Transfer of assembly structure and part names, – Transfer of “meta-data” such as material data, – Transfer of additional data such as part contacts. p STAR Konferenz Deutschland 2009, 9-10 Nov. 2009 9
Where are you starting? Tessellated Surface Data: Standard Import Support for all standard • tessellated file formats: .stl – .dbs – .nas – .pat – .inp (prostar) – … and some domain- • specific formats: .fro (Felisa) – .bif (Medina) ( ) – STAR Konferenz Deutschland 2009, 9-10 Nov. 2009 10
Where are you starting? Just an Idea: 3D-CAD Solid Modeler • 3D-CAD is a parametric solid modeler integrated with STAR-CCM+ STAR-CCM+. • Use it for: Building Quick “what if” • scenarios from scratch Modifying imported CAD • geometry Creating artificial geometry • to use in meshing and to use in meshing and reporting • Fully coupled with STAR- CCM+ engine for rapid design optimization design optimization STAR Konferenz Deutschland 2009, 9-10 Nov. 2009 11
How is your model organized? Once your data is in STAR-CCM+ we aim to provide • flexible tools to organize your data flexible tools to organize your data Data STAR-CCM+ Solution CAD/PLM assembly data Parts Hierarchy PLM material data Imported “meta-data” Logical part grouping Part tags Complex multi-region models Topological region splitting and automatic imprinting STAR Konferenz Deutschland 2009, 9-10 Nov. 2009 12
How is your model organized? CAD/PLM Assembly: Parts Hierarchy STAR Konferenz Deutschland 2009, 9-10 Nov. 2009 13
How is your model organized? CAD/PLM Assembly: Assembly Meshing/Analysis Imported • parts/assemblies are associated with Regions and Boundaries. All existing meshing • models can then be applied directly to the geometry. t Underlying CAD • definition used during wrapping and surface i d f remeshing to preserve fidelity to original model model. STAR Konferenz Deutschland 2009, 9-10 Nov. 2009 14
How is your model organized? PLM material data: Imported ‘Meta-Data’ • Any part data stored in PLM files can automatically be associated as “Meta-data” on associated as Meta-data on imported parts. • Examples include: • Material data • Modeling/meshing properties • Manufacturing information information • Stored meta-data can be accessed via scripting or GUI filters. STAR Konferenz Deutschland 2009, 9-10 Nov. 2009 15
How is your model organized? Logical Part Grouping: Part Tags • All parts can be assigned any number of flexible, user-controlled tags. t ll d t • Tags represent potentially overlapping grouping of parts with common parts with common properties. • Tags can be included with custom icons for quick visual reference. • Tags can be accessed by scripting or GUI filters.
