IcePro 3.1:
The New Pro/Engineer-Icepak Direct CAD Interface
IcePro 3.1, the new Pro/Engineer-to-Icepak interface, builds on its successful integration of CAD
software with Icepak’s thermal modeling software. The IcePro user can take advantage of many
of Pro/Engineer's CAD and database features. By allowing the user to use simplification tools
available in Pro/Engineer itself, the time required to get thermal models from CAD systems is
reduced dramatically. The philosophy of the integrated Pro/Engineer CAD interface is to take
advantage of design engineers' expertise in using Pro/Engineer to define the thermal model.
IcePro Features
Key Attributes in IcePro 3.1

Auto Export
o Allows you to configure export to suppress/identify features
o Auto-export to convert the ProE model to an Icepak model
o Show un-exported features

Image as viewed in ProEngineer
In addition, the manual export can also recognize extrusions, split polygons and preserve the
ProE model tree. The features introduced in v 3.0 of the interface have been retained.
Key Attributes in IcePro 3.0
1. Easier object/face selection procedure through elimination of the surface/object
abstraction procedure
Enhanced circular or rectangular geometry selection through curve selection
2. Direct import of material property from Pro/E to Icepak
3. Retain the dimensional unit information from Pro/E
4. Easier procedure for cylinder/polygonal object selection
The objects highlighted in red show single-click polygonal object selection
5. List manager – manage/edit/delete objects selected in Pro/E before exporting to Icepak
The List Manager is shown deleting objects
All of the following features in Version 2.0 have been retained in IcePro 3.0 and several feature
improvements have been made as referenced above. The details for Version 2.0 are:
Version 2.0 of the Pro/E-Icepak direct CAD interface contains features that drastically reduce
the time required to transfer a CAD model from Pro/E to Icepak. You can now export Icepak
models from individual parts, directly from the assembly, or designate Icepak objects in individual
parts from within Pro/E. There's also a feature that allows you to write out data without rescanning the entire part/assembly.
New Features in Version 2.0
1. Icepak and Pro/E users can now use the new interface with both assembly and part files.
2. If you have repetitive objects (for example, heat sink fins, PCBs) in your part or assembly
files, you do not need to pick these entities one-by-one. The repetitive features will
automatically come into Icepak.
3. Major improvements to polygonal objects selection and how they were written out.
4. Create circular surfaces for fans and openings without actually creating the surface
abstractions, as long as you select the two common surfaces to create the object.
5. The xyz extends of the picked surfaces can now be used to define all prism blocks.
6. Easier and more flexible way to import inclined plates.
7. The new "Fast Write Data" button allows you to write data out without rescanning the entire part or assembly. This option should only be exercised if no
geometric changes have been made, since the Icepak button was first pushed
inside the current model.
8. The new feature "Remove All Objects" allows the user to select multiple objects
without having to push "Remove Object" button for each one of the objects.

QFin:
The Optimized Heat Sink Design and Analysis Tool
Fluent and QFinsoft bring you QFin to help take the guesswork out of your design process. This
software tool enables you to simulate every aspect of heat sink design and analysis. The software
is quick and easy-to-use, with a comprehensive database of commercially available heat sinks
and component casings as well as the ability to design a heat sink to your own specifications.
QFin Features:
General Program Capabilities
The core of Qfin 3 is an easy to use, parameterized, fully 3D designer, allowing the engineer to
model an assembly consisting of a heat sink with multiple fans inside a cabinet. Several
advanced air flow models ensure accurate boundary calculations, and an efficient direct solver
calculates accurate heat transfer in seconds.
Because assembly designs are fully parameterized, Qfin3 allows easy range solving and
optimization of virtually all design variables. Full histories are also available for both range solving
and optimization, so that each solved design can be inspected along with its solution.
Other noteworthy program capabilities include the following:







Comprehensive project and assembly management through the Qfin3 Browser
Easy import, export and emailing of projects and assemblies
Import of Qfin2 assemblies
Wizards for quick and easy creation of different types of heat sinks
Fully 3D modelling of cabinet, heat sinks, and multiple fans
Parameterized specification of fin and pin configurations
3D viewing of calculated boundary consitions (pressure, air speed, htc, etc.)

Full HTML reporting for solutions, range solves, optimizations, and transient solutions
Browser
The main Qfin 3 window is called the browser, and provides easy access to the following
functions:






Project and assembly management (including importing, exporting, mailing, copying)
Component management (heat sinks, fans, etc.)
Online documentation (overview, tutorials)
Program settings (user information for reports, unit systems)
Product support
Product license management
Qfin 3 stores all projects, assemblies and component geometries in its own internal data
repository. As such there are no "file open/save" kind of functions, but you can export and import
projects, assemblies, and components for transfer between users. To make this process even
easier, there is a one-click "e-mail selected project/assembly" function.
In the future Qfinsoft will also offer a module that will allow shared network repositories, where
engineers can share projects, assemblies and components (with password protection if required).
Designer
The new designer has a CAD-like interface and allows you to design a complete assembly,
including cabinet, heat sink, and fan geometries at once. Solving is done directly from within the
designer, allowing for quick and easy design-solve-modify-solve cycles.
The 4 views are all OpenGL based and can be independently configured and rotated. As an
example, during normal design 3 of the views can show orthographic front, top, and side views,
while the 4th shows a 3D view. After solving the 4 views can all be set to perspective projected
3D mode, showing air speed, ambient temperature, heat transfer coefficient and solution
temperature respectively.
All elements of an assembly design are parameterized, allowing range solving and optimization
using virtually any design variable available in the model.
Other features of the designer include:



Tree based view of assembly and model
Selection of geometry using tree or directly in 3D view
All elements of model visible in 3D view, including cabinet, fans, sources and local
boundaries





Customizable color selection for all geometrical elements
Direct solving, range solving, transient solving and optimization from within designer
Automatic snapshots of 3D view in all reports
Automatic mesh creation, overridable for each geometrical element
Fan positioning relative to heat sink
Solver
Qfin3 uses several advanced radiation and convection models to calculate boundaries very
accurately, as well as a very efficient direct solver for heat transfer determination.
The end result of all this advanced technology is that Qfin3 can solve most assemblies in a matter
of seconds, which is especially beneficial during range solving and optimization, where multiple
solutions must to be generated.
Other features of the solver include:







User selectable radiation calculations
Full user-specified ambient conditions (including pressure calculation from altitude)
Accurate forced convection modelling for each kind of fan setup (ducted or impingement)
Effective modelling of air flow from multiple fans
Automatic determination of fan operating point if fan curve is specified
Independent meshing of heat sink elements, allowing fine grained control of mesh sizes
in different parts of heat sink
Full HTML solution reports (soon to be fully customizable)
Optimizer
Optimization in Qfin3 has been vastly expanded and improved from Qfin2. Because assembly
designs are fully parameterized, virtually any model parameter can be selected as an optimization
variable.
Qfin3 also allows simultaneous optimization of multiple functions, as well as flexible specification
of multiple constraints.
Most solution variables, like pressure drop and average htc, are also available as selectable
"monitors" during an optimization run. Full reporting is standard, including full reports of each
design that was solved during the optimization process.
Various optimizer settings also allow the user to specify optimization stop conditions, as well as
cabinet constraint and resizing measures to be taken during optimization.
FLUENT is the world leading CFD code for a wide range of flow modeling applications. With its
long-standing reputation of being user-friendly, FLUENT makes it easy for new users to come up
to productive speed. Its unique capabilities in an unstructured, finite volume based solver are
near-ideal in parallel performance. To ensure that FLUENT is ready to deploy right out-of-the-box,
we have put it through a comprehensive program of industrial-strength testing.
