Data Analysis• Interactive cut planes for STAR-CCM+ VR

◦ Immersive exploration of simulation results for deeper and faster comprehension◦ Use cutting planes to examine variations in scalar quantities in any scene

▪ Position cutting planes at any location and angle▪ Create persistent cutting planes for later review

• ◦ Requires a resampled volume derived part used in a scalar displayer▪ By default the resampled volume visibility is turned off

- Visibility can be restored with a new option on the handheld menu controller panel



• Accumulative data series charting D1436, D3009, D3455, D3507, D3983, D4579◦ Quickly extract an additional level of information

▪ Work with existing plot data already stored your in .sim files▪ Fewer reports, monitors and plots may be needed in new simulation efforts

◦ Flip back and forth between instantaneous vs accumulated results for each individual data series▪ Works for all chart types: XY Plot, Monitor, Histogram▪ Accumulation of values works for either iteration or timestep▪ Works with volume or solution history representations

◦ Simple example: Cyclone separator▪ Create incident mass flux reports/monitors/plots at top (escaping) and bottom (collecting) outlets▪ Switch between instantaneous mass and accumulated mass passing thru outlets with a simple

toggle▪ Plots at right, in figure below, show as a function of time:

- Mass escaping from top outlet- Mass currently in cyclone separator- Mass collecting from bottom outlet

• Monitor-based statistical reporting D405, D1099, D1232, D2928, D3279◦ Apply statistical treatment to existing Monitor data sources with this new Statistical Report type



◦ Statistics can be provided for an existing monitor to return:▪ Mean, Minimum, Maximum, or Sum

◦ Sample collection frequency can be set to all or limited to last N samples◦ Sample collection can be restarted using a monitor waypoint update event◦ Statistics can be based on either iteration or time step◦ Statistical Analysis of an Arrow micromixer highlights enhancement capabiities

Application Specific ToolsSTAR-ICEElectronics Cooling

STAR-ICE• Setup of "charge motion" simulations

◦ Perform more advanced in-cylinder simulation studies that examine the injection of fuel and the fuel/airmixing process▪ Automatic setup of common models▪ Easy setup of multi-nozzle hole injector geometry and operating conditions▪ Selection of fuel▪ Automatic setup of common post-processing



• New simulation diagnostic outputs◦ Better understand the operation of STAR-ICE and how the simulation is proceeding, facilitating the

transition from other tools and aiding in diagnosing mis-behaving models▪ CPU and elapsed time reports▪ Plot showing time step variations during the engine cycle▪ Plot showing mesh count and remap events during the engine cycle

• New run-time confirmation outputs◦ Confirm complex inputs are producing correct behavior and understand when the simulation deviates

from applied conditions and why▪ Plots of I/O boundary conditions plots (pressure, temperature, mass flow)▪ Plot showing time step variations during the engine cycle based on user-specified inputs

• Clean up of STAR-ICE parameters D4766◦ Exposed the default surface temperature parameter in the STAR-ICE Parameters panel



◦ Removed various parameters which users shouldn't edit from the STAR-ICE Parameters panel

Electronics Cooling• In-situ parameter creation

◦ Simulation parameters can be created at their point of use, in a single action▪ Streamlines your workflow when setting up parametric design studies▪ If you input an unrecognised parameter name, E-Cool gives the option to create a new parameter

with this name, and assign it automatically
