TES International has officially made its third thermal analysis tool available through the Altair Partner Alliance programme. TESuite uses a hybrid approach to combine the capabilities of TES’ other software, ElectroFlo and ThermoFlo, to provide an even more efficient solution. TESuite differentiates itself through its capability of coupling both a rapid one-dimensional (1D) and a highly accurate three-dimensional (3D) computerised fluid dynamics analysis on components as desired by the analyst. This provides the freedom to utilise a highly accurate physics-based analysis on the most relevant components, with a rapid network analysis available for use when adequate. With these features available, the resource requirements are dramatically reduced, while the necessary quality is maintained to build an accurate model of the system.
