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

Within a CAD system: STAR-CAD Series
- STAR-CAD allows CAD experts and designers to run flow
and thermal solutions from within their CAD application and thermal solutions from within their CAD application.
- STAR-CAD product is being refactored to operate as a full
client of STAR-CCM+:
– More robust, more efficient, more full-featured!

Within a CAD system: STAR-CAD Series Advanced Modeling
Step 2: Launch STAR-CCM+ client from STAR-CAD GUI, attached to existing server Step 1: Create model in CAD package and set up basic analysis settings using STAR- CAD “Analysis Tree” attached to existing server. Step 3: Set advanced physics in STAR-CCM+ client. Need to enable advanced physics option not exposed in STAR-CAD Step 4: Close STAR-CCM+ client and return to STAR- CAD environment to CAD environment to continue analysis. Step 5: Make design change in CAD package and rerun
- analysis. Advanced physics
settings are maintained.

- 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

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.

Logical Part Grouping: Part Tags
- All parts can be assigned
any number of flexible, t ll d t user-controlled tags.
- Tags represent potentially
- verlapping 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.

Enforce Best Practices: Simulation templates
- Users can now set up models with mesh
generation and physics objects defined but no geometry.
- These can then be saved and reused as
templates for modeling.
- Any geometry can be read in, associated with
the pre-defined modeling objects and simulated.
- Use cases include:
– Sharing/enforcing “best practices”
Improving uniformity of results within
– Improving uniformity of results within
departments
– Improving access to the code by less
trained designers trained designers.

Customization/Automation: Flexible Java-based scripting
- Java-based scripting allows access to all
functionality of STAR-CCM+ and the Java functionality of STAR CCM+ and the Java programming language.
- Scripts can range from simple “build and run”
to complete custom applications with GUI.
- Custom programming can be imported as
modules within STAR-CCM+ to fully integrate modules within STAR CCM+ to fully integrate with existing GUI.
- Java scripts can directly access 3rd party file
formats like Excel, Powerpoint, and Acrobat for import and export of data and results.
