What Is STAR-CCM+?
STAR-CCM+ provides the world's most comprehensive engineering physics simulation insidea single integrated package. Much more than just a CFD solver, STAR-CCM+ is an entireengineering process for solving problems involving flow (of fluids or solids), heat transfer, andstress. It provides a suite of integrated components that combine to produce a powerfulpackage that can address a wide variety of modeling needs.These components include:????????
3D-CAD modelerCAD embeddingSurface preparation toolsAutomatic meshing technologyPhysics modelingTurbulence modelingPost-processingCAE Integration
STAR-CCM+ is based on object-oriented programming technology. It is designed to handlelarge models quickly and efficiently using a unique client–server architecture that seamlesslymeshes and simultaneously solves and post-processes over multiple computing resourceswithout requiring additional effort from the user. STAR-CCM+ recently became the firstcommercial CFD package to mesh and solve a problem with over one billion cells.
The object-oriented nature of the code can be seen in the user interface. An object tree isprovided for each live simulation, containing object representations of all the data associatedwith the simulation. The objects presented on the simulation tree reside on the server, whichcan run as either a serial or a parallel process. A client interface connects to a server, anddisplays the simulation objects available on that server.
3D-CAD Modeler
3D-CAD is a feature-based parametric solid modeler within STAR-CCM+ that allowsgeometry to be built from scratch. The geometry created with 3D-CAD is stored as 3D-CADmodels, which can subsequently be converting to geometry parts for integration with themeshing and simulation process. A major feature of 3D-CAD is design parameters, whichallow you to modify the 3D-CAD model from outside of 3D-CAD. These allow you to solvefor a particular geometry, change the size of one or more components, and quickly rerun thecase.

CAD Embedding
STAR-CCM+ simulations can be set up, run and post-processed from within popular CAD andPLM environments such as SolidWorks, CATIA V5, Pro/ENGINEER, and NX.STAR-CCM+’s unique approach gets you from CAD model to an accurate CFD solution morequickly or more reliably.
CFD results are linked directly to the CAD geometry (a process called associativity). After anymodification in the CAD model the simulation results can be updated almost instantly byclicking the “update solution” button, allowing the rapid and thorough investigation of thedesign space.
Surface Preparation Tools
At the heart of STAR-CCM+ is an automated process that links a powerful surface wrapper toCD-adapco’s unique meshing technology. The surface wrapper significantly reduces thenumber of hours spent on surface cleanup and, for problems that involve large assemblies ofcomplex geometry parts, reduces the entire meshing process to hours instead of days.
The surface wrapper works by ‘shrink-wrapping’ a high-quality triangulated surface mesh ontoany geometrical model, closing holes in the geometry and joining disconnected andoverlapping surfaces, providing a single manifold surface that can be used to automaticallygenerate a computational mesh without user intervention.
STAR-CCM+ also includes a comprehensive set of surface-repair tools that allow users tointeractively enhance the quality of imported or wrapped surfaces, offering the choice of acompletely automatic repair, user control, or a combination of both.
Automatic Meshing Technology
STAR-CCM+’s single integrated process provides the fastest, most automatic route fromcomplex CAD to CFD mesh. Advanced automatic meshing technology generates eitherpolyhedral or predominantly hexahedral control volumes at the touch of a button, offering acombination of speed, control, and accuracy. For problems involving multiple frames ofreference, fluid-structure interaction and conjugate heat transfer, STAR-CCM+ canautomatically create conformal meshes across multiple physical domains.
An important part of mesh generation for accurate CFD simulation is the near-wall region, orextrusion-layer mesh. STAR-CCM+ automatically produces a high-quality extrusion layermesh on all walls in the domain. In addition, you can control the position, size, growth-rate,and number of cell layers in the extrusion-layer mesh.
