Airpak is an easy-to-use computational fluid dynamics (CFD) tool that lets the user accurately model airflow, heat transfer, contaminant transport, and thermal comfort in ventilation systems as well as external building flows. It eliminates the guesswork in designing ventilation systems. Airpak can reduce the risk for new designs and improve the efficiency of current designs while saving time and money. Easy Animation Export Airpak 2.0 makes it unnecessary for users to purchase additional software so that they can export the computer animations of their results. Airpak exports the animation in MPEG, AVI, animated GIF or FLI file formats. "Exporting directly into an animation gives our users the fastest way ever to convert results into valuable marketing pieces," says Schwarz.
