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® 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, that are the subject of the investigation, the solution time can be reduced more than ten times.

Coolit® v.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.
