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

Where are you starting?

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

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” h ti mesh generation.

  • Continually working with
  • ur CAD partners to

i lit d improve quality and robustness of CAD import

PLM Data: Direct PLM import

  • Work is ongoing to support a tight

integration of STAR-CCM+ into a

Medina XML

PLM-enabled workflow.

  • Import of model data from PLM can

include:

JT Open PLM XML Others?

– Transfer of assembly structure

and part names,

– Transfer of “meta-data” such as Model Data

material data,

– Transfer of additional data such

as part contacts. p

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

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 t geometry.

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.

How is your model organized?

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.

Batch post-processing

  • All STAR-CCM+ visualization/post-

processing capabilities can be accessed via batch programming.

  • All desired plots, reports, scenes, and

animations can be created automatically upon completion of a STAR-CCM+ run.

  • Resulting files can be directly embedded

in PowerPoint, excel, etc.

  • Other results integrations planned include

Adobe Acrobat and JTOpen.

  • The result can be a completely automated

p y process from CAD to report. JT Open

What is your CAE workflow?

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.

What is your CAE workflow?

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.
