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.

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 interactive "live" and "post" processing needs to be flexible and dynamic. Scenes can be easily created and modified to examine your results. Scene content is flexible - you can illustrate surfaces of interest in your simulations and an extensive collection of derived parts, like the re-sampled volume (for Volume rendering), streamlines, and section cuts to name a few, gives you the ability to deeply interrogate your results. From a workflow standpoint, the task of composing a scene is simplified with our drag-and-drop functionality, letting you quickly display scalar and vector results. There’s no limit to how many scenes you can create and scenes are dynamically updated 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+. With this release, we have dramatically expanded the overall capabilities of STAR-View+. This starts with the ability to export scenes using compression, making them 2X-3X smaller than before. it's also possible to append data from different scenes or even different datasets for easy comparisons. The standalone STAR-View+ viewer has thumbnail previews to let you easily navigate content. New controls let you animate content such as streamlines and swept plane surfaces while you are interactively moving your content. And, it's possible to save animations and hardcopies for later review with other design teams. The STAR-View+ plugin for Microsoft PowerPoint has also been updated to let you easily navigate content and animate results right in your PowerPoint presentations.
Interactive performance continues to be a core development area for us. With our current release, we have added the ability to effectively control and utilize your local GPU resources - by this we mean taking full advantage of your graphics card. This feature enhancement is aimed at drawing (or rendering) images faster, using your local graphics resources, with the end result being a better interactive experience for you when working with STAR-CCM+. At the highest level of GPU utilization, we have seen a 30-fold increase in interactive performance.
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. Reporting frequency is controlled with updating which can be triggered through several mechanisms. 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. High quality plots with control over legend placement and many controls let you customize your plots to best meet your needs. While our drag-and-drop functionality lets you add parts directly to any existing plot, streamlining how data is managed - as a result, gathering and presenting data is easy and fast. 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 Simulation Assistant tool.
