STAR-CCM+ has the tools for Effective Visualization and Analysis
Choosing a best design from many simulation runs or running more simulations is decided when your results are critically reviewed quantitatively and qualitatively. STAR-CCM+ provides an extensive range of powerful visualization tools to allow you to make your decisions easier, quicker and with confidence.
  • High angle of attack re-entry simulation of the NASA X-34 with adaptive meshing for off-body shock capture: STAR-CCM+ offers a comprehensive range of efficient solvers for flow regimes from low speed up to hypersonic (whilst the fluid remains a continuum). Image courtesy of TLG Aerospace.
  • At the heart of STAR-CCM+’s post-processing toolset is the ability to extract and analyze engineering data. Here, an harmonic balance (HB) simulation was performed on a multistage axial compressor and the relative Mach mumber on the blades was displayed.
  • STAR-CCM+ has an extensive range of visual analysis tools to help deliver insight from the results. Here for example, post-processing tools were used to help visualize the ground effect and the complex vortex flow around the body of a high speed TGV train.
  • STAR-CCM+ was used to perform the aerodynamic analysis of a Wilson soccer ball in order to better understand its side force effect. The image shows streamlines in the wake behind the soccer ball.
  • Innovazione used STAR-CCM+ to perform an aerodynamic analysis of a sport touring motorcycle. Image courtesy of Roberto Di Francesco, Innovazione.
  • This image shows the tangential velocity fields and surface pressures from aerodynamic interactive coupling effects between unmanned aerial vehicles flying in close proximity to each other.

Effective Visualization

Effective postprocessing needs to be flexible and dynamic.  Our drag-and-drop functionality lets you quickly and easily add as many different displayers (to show scalar or vector quanities) as you want into a scene.  There’s no limit to how many scenes you can create and scenes are dynamically updated, giving you constant feedback, while your simulation is running.  This lends itself ideally to process automation – you can customize multiple scenes to illustrate your geometry, highlight your mesh, and provide multiple detailed views of your process variables.  Annotations give you a way to place text, logos, plots and even other scenes into the same window letting you customize your postprocessing to exactly fit your needs.  

A direct export from any scene produces files that are compatible with our free standalone 3D viewer, STAR-View+.  The scene exports are much smaller in size than the simulation files they are derived from and this lets you easily share simulation results throughout your organization.  STAR-View+ can be embedded in Microsoft Word, Excel and PowerPoint giving you added options for communicating your results.  

Recently, we introduced Volume Rendering to let you create highly advanced illustrations of your simulation data.  With this release, we have extended our Volume Rendering capability even further with more realistic lighting control.  And, a new colormap editor gives you the ability create and modify your colormaps giving you the ability to make high impact, descriptive visualizations that can be quickly understood by all members of your organization.  

Effective Analysis

Visualization provides qualitative insight to your simulations  –the quantitative complement for comparison, validation and verification of your simulation results is delivered in three function categories:  reporting, monitoring and plotting.  Reports generally return a result based on the specification of a scalar and parts (including derived parts).  Reports can be run interactively and provide the content for monitors which can be evaluated continuously during simulation runs.  Monitor output forms the basis for monitor plots showing you how your reports change versus iteration or time step.  Histogram and XY plots round out the plotting capabilities.  As your simulation runs and the solution evolves, your data can be continuously interrogated and solver settings can be changed on the fly. This means that you are always in control, ensuring result accuracy and efficient computer resource usage.

Critical analysis of your simulation results needs to be easy and comprehensive.  Our drag-and-drop functionality lets you add parts directly to any existing plot.  Reporting frequency is controlled with updating which can be triggered through several mechanisms.  And you can easily place plots into any scene giving you full flexibility to integrate and customize your reporting requirements. 

Having the ability to standardize your analysis & reporting across many simulations is important.  This can be done by creating re-usable templates.  It is possible to further automate your process and capture your best practices using Java macros and our recently introduced Simulation Assistant tool.
