Thermo-fl uid analysis softwareThermo-fl uid analysis software is a simulation tool used for analyzing

complex thermal/fl uid phenomena. Since software simulation enables

predicting performance without creating a hardware prototype, the

tools can be used early in the planning state of product development

to sift through preliminary design concepts. Simulation can also be

used to predict performance of products where it is diffi cult to make

experimental measurements. In addition, simulation software can

be used to visualize invisible fl uid fl ow and heat transfer. This results

in increased engineering understanding while providing a vehicle for

communicating this knowledge to non-experts.

Thermo-fl uid analysis software is indispensable for "Front-loading"

product development to ensure the best product concepts

are identifi ed early in the design process. Design quality will be

improved during the conceptual design phase by conducting basic

studies of fl uid and thermal phenomena that directly aff ect product

performance. During the detailed design phase, analyses are

conducted under conditions similar to what the actual product will

experience. From this work, design engineers can understand the

source of problems that limit performance and investigate alternate

design solutions before production begins.

One of the foremost expectations of today's successful product driven companies is that they bring high value-added products, that meet customer

needs, quickly to the market. In addition, successful companies proactively identify application scenarios that could result in unsatisfactory performance,

product failures, customer dissatisfaction and/or develop design solutions that mitigate the potential risks.

What is important in product development?

Cradle off ers two diff erent types of thermo-fl uid analysis tools:

scSTREAM (and HEAT Designer for electronics cooling) and SC/Tetra.

scSTREAM and HEAT Designer use structured meshes while SC/Tetra

uses an unstructured mesh.

A structured mesh is simple and easy to construct. This mesh is

comprised of many small cuboids so it can only approximate curved

or angled surfaces. It is most useful for applications where tiny details

and surface curvature or angles do not have a strong eff ect on the

overall fl ow fi eld. Examples of applications for structured mesh

include electronics cooling, HVAC, and architecture.

Unstructured mesh contains more complex element shapes

(tetrahedron, pentahedron, and hexahedron). These elements

provide a fl exible way to represent curved surfaces. As a result,

SC/Tetra is used for applications where precise representation of the

geometry is critical. Examples of unstructured mesh applications

include fan blades and automotive aerodynamics.

Analysis Procedure

Preprocessing❶ Create analysis model, ❷ Set analysis conditions, and ❸ Generate mesh

SolvingFlow/thermal calculations are performed using input data created in the Preprocessor. During the

computation, calculation status can be monitored. The amount of time required for the computation

depends on the size of the model (number of mesh elements), quality of the model, and hardware.

A parallel solver is available for reducing the computational time of large-scale models.

*See page 10 (HPC Solution) for more information about parallel calculation.

PostprocessingThe solver outputs fi eld data for visualization using the Postprocessor. This permits examining fl ow,

temperature, pressure, and other analysis results. Visualized results can be converted to images,

animations and/or CradleViewer fi les for later use.

*See page 11 (Postprocessor) for more information about Postprocessor.

*See page 9 (Utility) for more information about CradleViewer.

In scSTREAM and SC/Tetra, analyses are performed using a set of three applications Preprocessor, Solver, and Postprocessor.

About the softwarescSTREAM thermo-fl uid software has serviced the electronics and architectural industries for thirty years. HEAT

Designer is based on scSTREAM and is specially developed for thermal design of electronics products. Both software

enable non-experts in the thermal sciences to conduct thermo-fl uid analyses with ease by providing modeling

capabilities and wizard-based interfaces for setting conditions. Moreover, consistent with anticipated needs for larger

and larger models, these software are already adapted for large scale calculations using parallel computations that can

accommodate up to one billion mesh elements.

Multiblock & Meshing

A complex model requires many mesh elements to describe its geometries. Multiblock meshing, which minimizes the range of mesh refi nement, is an essential feature for analyses of large-scale models.

Computing Speed

A structured mesh ensures high speed computations and superior stability. Structured meshes are ideal for simulations where fi ne geometry details do not greatly aff ect the overall fl ow fi eld and heat transfer.

Modeler

Includes modeling functions ranging from simple building blocks to a CAD-like modeler. Features pre-built fan and heat sink models for easy set-up without having to use complicated CAD models.

CAD Interface

A standard feature includes the capability to directly import native data from a variety of CAD software as well as intermediate formats such like Parasolid, STEP, IDF, STL, DXF, IGES, ACIS and Gerber circuit board data. Direct interfaces with Revit Architecture and ArchiCAD are available as options.

Collective Setting

A detailed analysis requires specifying parameters for all the parts used. Setting these conditions can be tedious and time consuming. A CSV fi le can be used to specify collective setting of conditions which saves time and increases effi ciency.

About the softwareSC/Tetra is general purpose, unstructured mesh software that is effi ciency and high fi delity focused for solving fl uid/

thermal problems involving complex geometries. It provides a wizard based user interface that guides the user through

the step by step set-up process. SC/Tetra also provides a robust interface which directly imports native data from a

multitude of CAD software as well as various intermediate fi les. SC/Tetra contains sophisticated models for simulating

complex physical phenomena.

High speed, Automatic Mesh Generation

The mesh can be generated automatically after setting the size and density of the octants. The mesh generation process is adapted to parallel processing enabling large-scale meshing to be completed in a short time.

Moving Object (ALE, Overset, Dynamical)

Analyses can be conducted on fans and pumps that involve active motion of objects as well as passive motions where object motions are due to external forces.

CAD Interface

Native data from various CAD software can be directly imported. This simplifi es importation by eliminating the need to convert the CAD data into an intermediate format which can result in the loss of geometry information.

Mesh Adaptation Analysis

Mesh adaptation enables automatic optimization of the mesh size and density in regions where variations in fl ow and temperature are prominent. The user only needs to set the targeted number of mesh elements.

Compressible Flow Analysis(Pressure-based, Density-based)Analyses can be conducted on high speed fl ow (up to Mach 10), shockwaves, and rarefi ed fl ow at low pressure.

Automatic Cleaning

The automatic cleaning function fi nds defects in CAD data and automatically repairs interfering faces and multi-edges.

Automatic Defi nition of Material Properties and Condition Regions

Part names and colors confi gured in CAD can be inherited and used to defi ne material properties and condition regions automatically. This function is helpful when an analysis model contains many parts or is repeatedly used for case studies.

Extraction of Fluid Regions

CAD software is usually used to create the geometry of the solid parts. CFD is used to model the fl uid region surrounding these parts. The extraction function automatically creates the fl uid regions from the CAD data.

Spending too much time fi xing CAD data?CADthru can fi x problems with CAD data making it suitable for analysis without going back to the CAD software.

About the softwareCADthru is a data translation tool used to prepare CAD

data for CFD analysis. CADthru's robust functions enable

fast and automatic repair of geometric and topological

data defects that are artifacts of the CAD software.

PostprocessorViewing analysis results using the Postprocessor is a key to obtaining the understanding necessary to improve product design. In many situations, experimental measurements are diffi cult to obtain, especially those within complex parts or when exposed to severe operating conditions. In contrast, viewing results in the Postprocessor is always easy to do.

The Postprocessor can be used to visualize data in various ways to better understand heat and fl uid fl ow and provide a vehicle for sharing information. This leads to productive discussions and visual presentation of results. Within the Postprocessor, results can be displayed and compared. Results can be analyzed using graphs and tables. In addition, the Postprocessor is compatible with parallel processing, which enables fast and effi cient viewing of large-scale analysis results.

VB InterfaceCradle analysis software can be controlled from external applications, including Microsoft Offi ce, using the COM interface promoted by Microsoft. This interface is called the VB interface (VBI).

Using VBI, various tools can be created, depending on needs, to automatically perform certain operations. For example, a tool can be created to simplify the settings for an air conditioning analysis (see fi gure), or to automatically write analysis reports.

・Visualization features (examples) - Vector plot - Contour plot

 - Streamlines - Pathlines (SC/Tetra only)

 - Isosurface - Oil fl ow ・ Processing features (examples) - Automated creation of animation

 - Storing displayed data

 - Comparison and arithmetic operations between multiple

results

 - Azimuthal projections (meridian plane view)

 - Operations (integration, function registration)

・ Applications (among others) - Simplifying settings for air-conditioning analyses

 - Writing analysis reports automatically

 - Automating a series of analysis operations

 - Automating a process of creating 3D model from 2D model
