Cooling simulation helps reduce design time
Electronics cooling simulation is helping a major aerospace manufacturer reduce design time while minimising system weight, according to Dr Samir El-Khabiry of Illinois-based Hamilton Sundstrand.
Desktop simulation of cooling pays dividends
In an economy where negative growth is all-too-normal, Fluent reports dramatic and sustained growth in its computational fluid dynamics software products.
Ansys Icemax technologies are now part of the Ansys suite, from the company's 2006 acquisition of Fluent.
The release aligns with the Ansys focus on powerful industry solutions, based on the company's commitment to simulation driven product development.
The Ansys Icemax user interface allows users to import multiple designs within the same model, use automatic alignment tools and analyse the assembled design as a unified structure.

Developed to address signal integrity issues in today's high-speed IC package designs, Icemax provides substrate designers and electrical analysts with a simple highly automated modelling environment.
"Stacked packages are becoming increasingly common, especially in the handheld and wireless space".
"Existing design flows in most semiconductor companies are set up to analyse individual layouts separately and then connect them up in the system-level electrical model".
"For 3D stacked packages, and in general system-in-package designs, this approach has obvious limitations", says Chetan Desai, Ansys Icemax Product Manager.
"The electrical model has to be extracted by accounting for all possible interactions within the 3D package assembly at the field solver level".
"Appropriate return paths across package interfaces have to be accurately detected for generating the final equivalent circuit".
"Ansys Icemax 3.0 technology helps engineers realise this objective".
The software enhancements are complemented by additional optimisations of core meshing and field solver technologies that have been integral to earlier product releases.
Improvements have been made to simplify the specification and detection of return paths in the package and PCB.
Batch processing is a major new addition to the solver, providing further automation in the design flow.
Ansys Icemax 3.0 software will continue to operate on multi-CPU machines as well as 64bit Windows and Linux platforms, helping customers easily analyse high pin-count packages with complex power and ground structures.
New visualisation capabilities include custom widgets for layer-by-layer model display and finite volume mesh display.
Other key enhancements include analysis of lossy dielectrics and specification of user-defined terminals in the Ansys Icemax model.
In addition to RLCG data, results can now be exported in the form of S/Y/Z parameters in industry standard touchstone format.
