CANONSBURG, PA – Ansys Inc. has released Version 4.3 of its Icepak electronics cooling design software. Direct representation of CAD geometries expands the ability of Icepak software to handle complex geometry, reportedly providing additional flexibility and a higher degree of automation while modeling complex shapes. Icepak 4.3 also has direct import of trace and via details from MCM/BRD and Gerber files of PCB layout, along with a new method to accurately represent these details.
 
The automatic hex-dominant mesher can be used to mesh CAD geometries quickly and efficiently. It is said to be a robust and highly automated unstructured mesh generator that can handle grids of virtually unlimited size and complexity, consisting mostly of hexahedral elements but including triangular, tetrahedral or pyramidal cells. In addition, Icepak 4.3 comes with enhanced libraries including thermo-electric cooler modules and new materials, modeling of temperature-dependent powers, enhanced macros and improved correlations for automatic specification of heat transfer coefficients.
