Volume of Fluid (VOF)• Implicit Multi-Step

◦ Accelerate VOF simulations by allowing a larger flow timestep size▪ Removes CFL limit in choice of timestep▪ Sub-steps for volume fraction within flow timestep▪ Cost of sub-step << cost of flow timestep

Application Specific ToolsIn-cylinder SolutionElectronics CoolingBatteriesE-Machines

In-cylinder Solution• Improved performance of rigid prism boundary layer morpher

◦ Improvements in total turnaround time thanks to new morpher parallel exchange algorithm▪ Influences all runs with rigid prism layers, a default since Simcenter STAR-CCM+ 2020.3 release▪ Greater gains in simulations with liquid film (up to 1.3x speed up)

• Automatic time-step size reduction for the first valve opening event◦ Increased stability in the early phase of the engine cycle with automatic reduction of time-step size

around the first valve opening▪ New sub-section of the Auto Time-Step Setting panel, addressing first valve opening, be it exhaust or

intake▪ Minor increase of total iterations with default values

• Volumetric control encapsulating the valve interface◦ Increased stability via mesh modification in the vicinity of the valve curtain interface

▪ Customizing surface mesh size and prism layer thickness at this location◦ Greater flexibility in volumetric control adoption with on/off settings

▪ Global parameter enables activation/deactivation▪ Function of valve lift closure tolerance – active in very low lifts

• Lagrangian Volume Source Smoothing Method active by default◦ Increased stability in models involving liquid fuel injection thanks to new defaults

▪ Volume source smoothing method activated by default once the injection model is on▪ Shell source smoothing method activated when liquid film is also active▪ Underlying cluster length value set to mesh size dependent value▪ New sub-section, under Solvers, to adjust the cell cluster length fraction

• Valve lift panel: cubic interpolation and new plotting options



◦ Increased accuracy in boundary condition and motion specification of engine valves through newinterpolation option▪ Smoother, non-stepped, valve velocity curves

◦ Reduced set-up errors with valve input quantities displayed live▪ Options to display in the Valve Lift XY plot: raw table, valve lift, and velocity▪ Functionality to show only valve currently open

• Constant mass flow rate for fuel injection◦ Increased usability through introduction of stepped Lagrangian fuel injection

▪ Addresses the previous limitation of using (X,Y) table with single-value Y column▪ Allows access to Start / End of injection parameters influencing the injection timing

◦ Reduced set-up errors thanks to an auto-updated plot▪ Mass flow rate table updated upon varying timing parameters and/or mass flow rate

• Export Conjugate Heat Transfer (CHT) data into separate files◦ Increased productivity by additional flexibility in the way conjugate heat transfer data is written out

▪ Generates separate files for different shell regions• Addition of stripped film evolution curve in the fuel mass plot

◦ Faster comprehension of simulation data by including the evolution of fuel droplet mass stripped fromthe liquid film

• Option to disable In-Situ Adaptive Tabulation (ISAT) with Relaxed To Chemical Equilibrium (RTCE)◦ Increased flexibility via option to deactivate on-the-fly tabulation for cases in which the method does not

lead to a speedup of complex chemistry

Electronics Cooling• Add annotations to scenes

◦ Improved understanding of results and model with ability to add annotations to scenes

Batteries• Simplified battery pack creation

◦ Improved productivity and reduced setup errors thanks to new setup options▪ Copy/Paste of battery modules now possible, allowing pack build-up in a few clicks▪ Series or Parallel module connection action

- Automatically connects battery modules in series or in parallel within the Circuits folder



• Import of Simcenter Amesim Equivalent Circuit Model (ECM)◦ Fast and automated RCR 0D model configuration with new Simcenter Amesim ECM data import

▪ Complements the existing Text Battery Model (TBM) file import◦ Prevents redundant and time-consuming ECM fitting task by leveraging existing data

▪ Re-use of fitting previously performed in Simcenter Amesim Battery Identification tool◦ Ensures model continuity across scales and scenarios for consistency of results

• Support of diffusion resistance for RCR 0D model◦ Expert option to specify an additional diffusion resistance as part of the RC element within the RCR 0D

model. It is the same diffusion resistance as specified in the RCRTable 3D model in Simcenter BatteryDesign Studio.

E-Machines• Simcenter Motorsolve e-machine design files import

◦ Simcenter STAR-CCM+ E-Machines Performance Workflow now supports import of e-machine designsfrom Simcenter Motorsolve, in addition to the existing support from Simcenter SPEED

◦ 1 click to access the e-machine geometries▪ e-Machine design geometry is automatically generated in 3D-CAD and creates 2 composite parts:

- 1 for the 2D electromagnetics problem - 1 for the 3D thermofluidic problem

▪ Faster electromagnetics physics setup thanks to automated assignment of materials in the partsmetadata field- A template sim file can be used to further automate the physics setup
