Modeling thermal and flow transients accurately is invariably difficult. Getting a solution takes
a long time and demands powerful computers. With the release of Daat Research's Coolit and
CoolitPCB v.14 CFD software, engineers now have the option of using larger time steps when solving
transients thereby reducing the solution time. For especially difficult large cases, in which fast
processes coexist with much slower processes, which are the subject of the investigation, the
solution time can often be reduced more than ten times.
Version 14 also benefits from Daat's ongoing CAD import improvement research. The new release
delivers enhanced CAD import quality, while simultaneously decreasing the required number of grid
cells and solution time. For added efficiency, the imported object geometry is stored in case
files, allowing the engineer to change import accuracy without reimporting the object.
Determining apriori whether flow is laminar or turbulent is not easy, even for experienced
mechanical engineers. For electrical engineers, who are often the most enthusiastic Coolit fans, it
is even more of a challenge. In v.14 Coolit offers a powerful assistant to help with this task.
Building on artificial intelligence techniques, the software analyzes specified flow and heat
sources, as well as boundary conditions to predict the flow regime. If the software-determined
regime is different from the one specified by the user, a warning is issued.
Coolit and CoolitPCB v.14 are shipping now.
