Application-Specific Tools

Simcenter STAR-CCM+ includes tools for specific industry applications. These tools shorten the time required

for creating and analysing typical cases that those industries require.

AR-ICE

STAR-ICE provides a dedicated interface within Simcenter STAR-CCM+ for simulating unfired internal

combustion engines (ICE) using transient moving-mesh methods. STAR-ICE can also simulate fuel injection

and the fuel/air mixing process.

Geometry

Import engine CAD and map to recognized parts: full or half-engine (with symmetry)

Physics

STAR-ICE uses a subset of physics models that are relevant for unfired ICE and charge motion cases:

• Time: transient calculations

• Time-step: constant or stepped table

• Solution domain: single-domain (gas)

• Material: nitrogen

• Heat transfer modes: conduction and convection (forced and buoyancy driven)

• Flow regime: turbulent (Realizable K-Epsilon Two-Layer All Y+)

• Equation of state: ideal gas

Conditions

• Geometry: full or half-engine (with symmetry)

• Initialization: import tabular pressure and temperature data

• Flow boundaries: pressure outlets using tabular pressure and temperature data

• Wall boundaries: thermal and wall surface specification

Motion

• Cylinder motion: calculates piston position from engine geometry and operating conditions

• Valves motion: import valve lift curves

Mesh

• Volume mesh: trimmed cell mesher (predominantly hexahedral cells)

• Prism layers: prismatic cells on walls for boundary flow accuracy

• Cell size: based on best practices

• Mesh refinement zones for chamfer and valves

Solver

• Segregated solver for flow and energy

Simcenter STAR-CCM+ v13.06 | Product Overview

Results

• Visualization of geometry, mesh, and solution data

• Access to solution data through plane sections that are positioned and oriented based on the engine

geometry

• Plots for characteristics of the in-cylinder flow, such as swirl, x-tumble, and y-tumble

Electronics Cooling

The Electronics Cooling Toolset provides a dedicated interface within Simcenter STAR-CCM+ for thermal

management simulation of electronics devices.

Geometry

• Geometry generation that is based on simple shape templates

• Import of IDF (Intermediate Data Format) files

• Import of CAD models from other CAD packages

• Transfer of CAD data from the Simcenter STAR-CCM+ CAD modeler

Physics

• Time: Steady-state calculations

• Solution domains: multi-domain (fluid and solid)

• Heat transfer modes: conduction, convection (forced and buoyancy driven), and radiation (wavelength

independent Surface-to-Surface (S2S) radiative heat transfer)

• Flow regime: laminar or turbulent (Realizable K-Epsilon Two-Layer All Y+)

• Equation of state: constant density or ideal gas

Conditions

• Environment: ambient boundary conditions

• Thermal specification: specification of material or specification of layers (PCB)

• Compact thermal models: resistor networks for chips

• Heat dissipation: volumetric heat sources

Mesh

• Volume Mesh: Trimmed cell mesher generates predominantly hexahedral cells

• Prism Layers: prismatic cells on walls for boundary flow accuracy

• Cell size: automatic calculation of target and minimum cell size that is based on overall model size

• Mesh Refinement: integrated features for mesh refinement to detect and capture complex geometries

• Local mesh controls: cell size customization on surfaces and within volumetric zones

Solver

• Segregated solver for flow and energy

• Solver under-relaxation

• Live monitoring of solution data

Results

•

Visualization of geometry, scalar, and vector quantities

• Access to solution data through streamlines, isosurfaces, and plane sections

• Residuals and XY plots

• Summary reports

Usability and Productivity

The Simcenter STAR-CCM+ client provides several features for an efficient and extensible simulation

framework.

Custom Simulation T

rees

Allows you to create smaller, more manageable simulation trees from selected objects in the main tree.

These custom trees are saved with the simulation file.

Simulation Tree Comparison

Provides a side-by-side comparison between two simulation files so that you can identify any differences.

Field Functions

Simcenter STAR-CCM+ supports an expression language by which you can create scalar, vector, or tensor

functions that vary in space and time.

• Includes an expression editor with built-in functions, predictive typing, auto-complete, and a preview

panel

Parameters

User-defined, spatially invariant scalar and vector constants. These parameters can be used in field

functions and can be referenced from any expression.

Filters

Filters, created from one or more logic-based queries, facilitate automation through repeatable object

selection.

• Queries are built from predicates (conditional statements) that are applied to a set of objects

• Queries support Boolean operators (AND, OR) and can be nested

Tagging

Tags provide a mechanism for grouping objects in almost every part of the simulation. You can create

custom trees and complex filters using tags.
