Coolit v.15 computational fluid dynamics software predicts airflow and heat transfer in electronics equipment and CoolitPCB v.15 printed circuit board board-level thermal analyses tool deliver an order of magnitude increase in user interface speed when working with complex CAD-imported objects. Major improvements to the solver include up to 40% solution time cut for most problems, and an up to a 50% boost for forced convection flows with difficult (multivalued) fan curves. Model construction efficiency has improved with the addition of a second window option to the system, which is particularly effective when using more than one computer monitor.

New functionality includes Joule heating, precise layer positioning for PCBs and support for circular/oval PCBs. Viewing computed results and generating reports is said to be easier due to enhanced CoolPlot integrated visualization tool. CoolPlot now includes new Probe components and the ability to write annotations on still images. Now automatically saves viewing configuration.

Other improvements introduced in v.15 are a streamlined user interface for fan modeling and increased convergence rates for free convection flows. The quality of exported videos and stills has also been enhanced. Both tools work with Windows.
