"Icepak 4.1's new 'Nested Assembly Meshing' allows the user to seamlessly bring far more detail into the model, to retain geometric shape fidelity, and improve accuracy, and it reduces mesh counts by 30% to 3 times compared to Icepak 4.0,” says Icepak product manager Rajesh Nair.

Building on a Strong Foundation—Users Respond

"Icepak's new ability of meshing assemblies separately has brought down my mesh count from 515,190 to 178,459. Thus, the results were achieved about three times faster and I investigated various design variations right within a day. I'm delighted and so was my boss!" says Christina Bohm of Motorola GmbH, Munich, Germany.

George Ozuna of Hewlett-Packard was one of the beta testers for Icepak 4.1. Remarking on his experience with the performance improvements, he says: “I had been using Icepak 4.0 when I was asked to conduct an analysis on a large server. The server was larger than a 1U unit and had no planes of symmetry to use for simplification. It was necessary to model all of the significant structure up stream of the areas of interest in order to get a good approximation of the airflow volume and direction. The model was first analyzed using the one level deep non-conformal meshing in Icepak 4.0. This model was too large to solve on a MS Windows OS system, due to the limitation of the 2GB of memory per MS-Windows process. Icepak 4.1 was made available to me and I was able to take advantage of the Nested Assembly Meshing option that allowed me to analyze a system that I couldn't using Icepak 4.0, and do it in more detail than previously possible.”

Speed and Other Productivity Enhancements

Icepak 4.1 also adds more than a dozen new and improved models and options to cap its performance enhancements. The list includes blower objects, new turbulence models, improved fan models, enhanced transient network modeling, and faster parametric solutions.
