Software Cradle Co. Ltd. has announced that its SC/Tetra Version 12, scheduled for release in June 2015, will introduce several new features including the coupling of SC/Tetra CFD software with Gamma Technologies’ GT-Power software for engine system simulation, allowing more accurate and detailed calculations for enhanced analysis and development. A GT-Power 1D simulation of the intake manifold could be replaced, for example, by an SC/Tetra 3D model, including compressible flow and mixing gas analysis. This is particularly important for an EGR (exhaust gas recirculation) simulation, according to Software Cradle, where a feedback is needed from the exhaust to the intake manifold. Performing the entire simulation in 3D is too expensive, while a 1D simulation cannot fully resolve the effects of 3D phenomena in the manifold. The coupling is set up using extensions to the standard, user-friendly SC/Tetra Condition Wizard, which lets the engineer systematically define the relationships between inflow/outflow conditions and chemical species in the two software packages. SC/Tetra can be employed for the design and analysis of engine systems, aerodynamics, climate control, acoustics, and numerous other automotive applications.
