Shown here is the screen representation of a battery pack cooling simulation in STAR-CCM+. The battery pack was designed in BDS and the flow and thermal simulation conducted in STAR-CCM+ using the Battery Simulation Module (BSM).
For heat transfer and conjugate heat transfer simulations, STAR-CCM+ offers a wide range of models, including solar, multi-band and specular thermal radiation (discrete ordinates or surface-to-surface) models. Here, STAR-CCM+ was used to compute the temperatures at component level inside a router...
To reflect the distributed nature of the modern project team, STAR-CCM+ is written using a client-server architecture. The server performs the numerical calculation while the client is used to control and visualize it. Client-server architecture allows for visualizing results as they are generated...
In this simulation of an F18 flying at high angle of attack, the flow around the plane is visualized with streamlines, the pressure is represented over the plane using a grayscale colormap, and the wingtip vortices are shown using an iso-surface of Q Criterion.
A wide range of flow regimes can be simulated using STAR-CCM+, including inviscid, laminar, turbulent (RANS, LES, DES), transition modeling. incompressible through to hypersonic. Visualized here are the Mach contours on a Scud missile.

STAR-CCM+ has the technology to solve a wide range of physics problems through its segregated or coupled solver. Using the interactive model tree, physics continua for each fluid or solid continuum can be easily defined in an intuitive, hierarchical way.
Physics capabilities include 2D, 3D, steady, implicit/explicit unsteady, harmonic balance, conjugate heat transfer, radiation, and solid stress among others. Flows with inviscid, laminar, and turbulent viscosities can be simulated. Turbulent models include Reynolds-Averaged Navier-Stokes (RANS), Large Eddy Simulation (LES), and Discrete Eddy Simulation (DES). Non-newtonian models are also available to help address the needs of Life Sciences and Food & Chemical Process industries.
To simulate components in motion, a variety of techniques such as Moving Reference Frame, Rigid Body Motion, and Overset Mesh are available, together with the DFBI six degree of freedom motion solver. Materials can be in a single phase, multi-component material and multi-phase mixture. To study solid particles, gas bubbles or fluid droplets, Lagrangian Multiphase and Discrete Element Method (DEM) models are available. Eulerian Multiphase model allows modeling of multiple gaseous or liquid phases. Other advanced physics models include combustion, free surface & cavitation, aero-acoustics, fluid-structure interaction, etc.
Once the physics continua is set-up, simulation can be run. STAR-CCM+ is unique as it provides full interactive control over the simulation process. It allows the user to watch the solution develop as the analysis is running and modify settings “live”.
The generation of flow visualization is important for analyzing the behavior of fluids/solids but being able to produce meaningful engineering data is key to effectively comparing designs and validating against experiment. To complement STAR-CCM+’s suite of visualization tools, an extensive range of options are available for solution monitoring as well as data analysis and reporting.
STAR-CCM+ has a comprehensive range of tools to report and dynamically monitor engineering data via plots. Report types range from simple field statistical data through to application-specific data analysis. These tools help to better converge to the desired result faster. As with the rest of STAR-CCM+’s single integrated environment, the data analysis may be setup as template in the sim file and further automated through java. This ensures consistent results and also the automatic generation of report files.
