ANSYS Icepak provides powerful electronic cooling solutions for thermal and fluid flow analyses of integrated circuits (ICs), packages, printed circuit boards (PCBs) and electronic assemblies.
Utilising the industry-leading ANSYS Fluent computational fluid dynamics, ANSYS Icepak is built upon the ANSYS Electronics Desktop (AEDT) graphical user interface (GUI). This provides a CAD-centric solution for engineers who can leverage the easy-to-use ribbon interface to manage thermal issues within the same unified framework as ANSYS HFSS, ANSYS Maxwell and ANSYS Q3D Extractor. Electrical and mechanical engineers working in this environment will enjoy a completely automated design flow with seamless coupling from HFSS, Maxwell and Q3D Extractor into Icepak for thermal analysis.
Engineers can rely on Icepak for an integrated electronics cooling solution for electronic applications ranging in scale from individual ICs to packages and PCBs, up to computer housings and entire data centers. The Icepak solver performs conduction, convection and radiation conjugate heat transfer analyses. It has many advanced capabilities to model laminar and turbulent flows, and species analysis including radiation and convection. Icepak provides a vast library of fans, heatsinks and materials to furnish solutions to everyday electronic cooling concerns.
Comprehensive Multiphysics Design Flow
ANSYS Electronics Desktop Platform lets engineers dynamically link Icepak with HFSS, Q3D Extractor and Maxwell to obtain electrothermal solutions. It’s as easy as a simple mouse click to map power losses from the EM tools to your design before executing thermal simulations. You can also tie in power integrity simulations in SIwave with Icepak thermal simulations.

Extensive Libraries for Thermal Physics
Icepak’s library contains an extensive collection of a wide range of useful materials that can be assigned to surfaces, solids and fluids. Icepak offers a streamlined electrothermal CAD-centric multiphysics solution by importing native MCAD & ECAD designs. Automated CAD geometry cleanup and healing functions, along with many editing options, facilitate easy simulation setup and analysis. A vast commercial library with a considerable number of Icepak 3-D fans and heat sinks is at the designer’s fingertips to solve typical thermal problems.
Convenient Slider Bar Meshing
ANSYS Icepak automates mesh generation while enabling you to customize the meshing parameters to refine the mesh and optimize trade-offs between computational cost and solution accuracy. Slider bar mesh settings let you make the mesh fine for objects where the temperature and velocity gradients are high and coarser where the gradients are small. These features make it easy to create a suitable mesh for performing thermal analyses. Additionally, arbitrary “Mesh Regions” let users assemble ECAD and MCAD that provide thermal solutions for complete product design.
Optimization in Icepak
Icepak provides native parametric “what if” and Design of Experiment (DoE) analyses on geometry, materials and power losses using ANSYS Optimetrics. For instance, you can easily calculate the electrothermal impact when you vary via drill size, pad sizes and/or input currents for a PCB via. The eddy current impact of transformers and coils are easily accounted for in the Maxwell-to-Icepak electrothermal analysis, ensuring the highest accuracy within a very easy-to-use and intuitive graphical user interface.
ANSYS Icepak software contains a full suite of qualitative and quantitative post-processing tools to generate meaningful graphics, animations and reports that can readily convey simulation results to colleagues and customers. Visualization of velocity vectors, temperature contours, fluid particle traces, iso-surface displays, cut planes and x–y plots of results data are all available for interpreting the results of an electronics cooling simulation. Customized reports, including images, can be automatically created for distributing results data, identifying trends in the simulation and reporting fan and blower operating points. ANSYS Icepak includes ANSYS CFD-Post for advanced post-processing and animation tools.
Simple and Intuitive Interface
To accelerate model development, ANSYS Icepak imports both electrical CAD (ECAD) and mechanical CAD (MCAD) data from a variety of sources. Icepak directly supports files that were created using EDA software such as Altium Designer, Cadence®, Zuken®, Sigrity®, Synopsys® , ODB++, IPC2581 and Mentor Graphics®. ANSYS Icepak directly supports the import of mechanical CAD data from neutral file formats including STEP and IGES files. ANSYS SpaceClaim enables Icepak to import geometry from all major mechanical CAD packages through the ANSYS Workbench geometry interfaces. Geometry imported from ECAD and MCAD can be combined into smart objects to efficiently create models of electronic assemblies.
