SummaryA major obstacle in performing real-world engineering simulations is how to retain the geometric fidelity of your product without unduly affecting simu-lation throughput. As model complexity increases, engineers may spend a majority of their time performing man-ual and repetitive tasks, such as:
• Cleaning and defeaturing dirty or incomplete computer-aided design (CAD) geometry
• Combining CAD models originating from various sources using multiple tools
• Preparing scripts to handle updating of design variants

Benefits• Easily integrate with existing design
processes by importing geometry from most leading CAD and PLM software
• Drive design modifications from the CAD or STAR-CCM+ environment with direct geometry transfer and bi-direc-tional associativity
• Easily create, modify and prepare geometry using the STAR-CCM+ inte-grated CAD modeler
• Combine CAD originating from vari-ous sources in a single STAR-CCM+ model
• Save engineering time with automatic geometry cleanup using surface wrapping
STAR-CCM+ geometry handling
Facilitate design processes by straightforwardly creating, modifying and preparing geometry
From geometry to solution: thermal simulation of an LED light bulb.
Eliminating these bottlenecks is critical so that engineers can spend their valu-able time doing what they do best: innovating.
STAR-CCM+ offers the solutionSTAR-CCM+ software helps you maxi-mize your productivity with robust and automated workflows that ensure complex geometries are ready to mesh in record time. The single integrated user interface facilitates geometry handling, including:
• Geometry creation: Efficiently create complex models using components from various sources, including exter-nal CAD packages as well as the STAR-CCM+ integrated CAD modeler, 3D-CAD
• Geometry preparation: Easily clean up geometry with tools, including auto-matic defeaturing in 3D-CAD, manual surface repair and surface wrapping
• Design exploration: Seamlessly parameterize and automate design changes enabled by the single inte-grated user interface and repeatable CAD-to-solution processes in STAR-CCM+

Geometry creation• CAD-Exchange: Import native and
neutral formats using the Windows® operating system or Linux operating system, including files from CATIA® V5 software, NX™ software, Parasolid® software, PTC® Creo® software, Autodesk® Inventor® software; and standard CAD exchange formats, such as Initial Graphics Exchange Specification (IGES), Standard for the Exchange of Product model data (STEP), STereoLithography (STL) and German Automotive Industry Association – surface data interface (VDA-FS)
• CAD-Clients:
> Direct geometry, reference data and coordinate system transfer and updates from CAD to STAR-CCM+ without intermediate CAD files
> Bi-directional connectivity to CAD/product lifecycle management (PLM) tools with access to, and modification of, design parameters in STAR-CCM+
> Remote execution for transfer of files on Windows and Linux from STAR-CCM+ to your CAD machine and vice versa
• 3D-CAD: Parametric, feature-based solid and surface modeling tool
> Create, modify and defeature native and imported CAD models
> Combine imported models with components created in 3D-CAD
Geometry preparation• Surface wrapping: Fully automatic
wrapping with projection to underly-ing CAD to provide a clean, closed surface ready for volume meshing
• Manual surface repair: Comprehensive manual repair tool for preparation of imported tessellated geometries
• Pipelined mesh operations:
> Extensive set of operations for geom-etry preparation, including Booleans, surface wrapping and multipart imprinting
> User-defined pipeline for operations
> Pipelined approach allows for auto-matic preparation of geometries irrespective of their sources
Design explorationDesign exploration with STAR-CCM+ is seamless and efficient due to:
• A robust and repeatable workflow from geometry to solution, eliminat-ing manual intervention
• A single integrated user interface, enabling easy setup of design param-eters and execution of design studies
• Fully automatic surface wrapping for handling of dirty geometries during design changes
• Bi-directional connectivity with native CAD through CAD-Clients, enabling design changes from either CAD or STAR-CCM+
