quickly▪ See the illustration below for snapshots from the STAR-CCM+ VR help, launched from and

navigable using the hand controllers



▪ Model manipulation using handheld controllers to let you- Push/Pull the model closer to or farther away from you- Dynamic Pan/Zoom- Fly In/Out to fly around your model

▪ Interactive or persistent massless particle emitters to study velocity or other vector fields- Requires a resampled volume derived part used in a vector displayer- In the figure below of a packed bed reactor,

* A persistent massless particle emitter is created* The massless particle size and display speed is modified* An interactive massless particle emitter is used to further explore flow around the catalyst

particles

▪ Interactive, multiple, persistent clip planes let you cut away content to look inside your model domain

◦ Currently unsupported features▪ Advanced rendering▪ Depth peeling (for high quality transparency)



▪ Line integral convolution▪ Scene grid annotations▪ Uniform screen settings for vector glyphs

◦ Known limitations▪ Animation sweeps when STAR-CCM+ VR is connected to STAR-CCM+ are possible but if refresh

rates are too low, VR rendering is automatically disabled▪ In the figure below, we are looking at different times for a simh animation playback of LMP content

- The total number of particles in this case is renderable with reasonable refresh rates

• Advanced rendering support for STAR-View+◦ Use STAR-View+ to review & share all your design results more effectively:

▪ Across your organization, and with your customers & partners◦ From STAR-CCM+, export .sce files, preserving advanced rendering settings

▪ No appreciable increase in .sce file size◦ In STAR-View+, advanced rendering controls are now exposed to offer:

▪ More realistic representation of results- Broadened comprehension for wider range of audiences- Better visual cues for more effective data visualization

• Specified transparency for plot lines◦ Review & communicate your plot findings more quickly by reducing visual clutter

▪ Emphasize more important information▪ De-emphasize less important information



◦ Change the transparency setting for any data series▪ Opacity exposed as a property setting on Line Style

- Range is from 0 (transparent) to 1 (opaque)

• Interactive plot legend docking◦ Customize your legend placement faster and more easily

▪ Plot legends can now be placed & docked interactively▪ Previously, legend placement could only be done by specifying numerical properties

◦ Visual cues, now provided during interaction, let you preview the docked location

• Improved usability for collocated values in min/max reports D1489◦ Previously, you could specify any number of collocated field functions (scalars or vectors) as a report

property to, for example,:▪ Find where the maximum temperature is for underhood cases▪ Return the mixing intensity for min/max concentrations in CPI mixing▪ Return local conditions for min/max Production Rates in surface chemistry applications

◦ Now, save time working with collocated functions using new field function support▪ getCollocatedValue($MinMax_Report, $collocated_FF, “partName”, {LITERAL|

PATTERN} )◦ Reduce the effort needed to return quantitative information

▪ Further your ability to effectively communicate results without having to write JAVA• Use cell surface derived parts for mass averaged reports

◦ Workflow is simplified by not having to take the trial & error approach needed to create a thresholdderived part

◦ Assists with near wall sub-volume averaging▪ Mass averaged reports show dominant near-surface trends for compressible flows



• Summary enhancement◦ Content population, by default, is all-inclusive now

▪ If you only want a plot and not it's full attributes, de-select the additional content

Application Specific ToolsSTAR-ICEElectronics Cooling

STAR-ICE• Significant performance increase

◦ Enhancements to the B-spline morpher lead to 1.1 - 1.2x performance improvement• Mass flow boundary condition

◦ Allows specification of mass flow at the inlet/outlet boundary in lieu of pressure data• Use standard tool bar button to run STAR-ICE simulations

◦ User is no longer required to run STAR-ICE via a right-clickcontext menu

◦ Custom macro is no longer required to run STAR-ICE fromDesign Manager

• Automatic time step control based on valve lifts◦ Allows specification of a default time step size along with

smaller time steps during various levels of valve lift tomaintain stability

◦ Supports time step specification in units of "s" or "deg"• Default selection of multi-component air model

◦ Allows the user to easily and quickly override the default single component specification to create amulti-component specification without changing the model selection

Electronics Cooling• Filtering individual instances in reference designator classes



◦ Speeds up simulation time by allowing the user to isolate and eliminate unimportant components▪ Gives users finer grain control over balance between speed / accuracy

◦ Enables the filtering of single components within a reference designator class when importing IDF files▪ Using the object selector, users can expand each Ref Des class and access each instance for

selection/deselection
