Software Cradle’s Cradle SC/Tetra v10 general-purpose, unstructured grid CFD software features a robust pre-processor with integrated geometry repair tools and a flexible, controllable, and fully parallelized hybrid grid generator that makes for exceptionally fast meshing. The pre-processor is combined with powerful physical models, a fast and memory-efficient solver, complementary fully parallelized post-processing tools, and a stand-alone viewer. The version incorporates new features and functionality: direct import is possible for most major native CAD formats into the integrated pre-processor including CATIA, Pro/Engineer, SolidWorks, NX, SolidEdge, and Inventor. IGES, VDAS, and ACIS formats are seamlessly imported. The software can accommodate models containing up to 1 billion elements. A new density-based solver for high-mach-number compressible flows using a fully coupled solver solves the mass, momentum, and energy equations simultaneously. A new VOF (Volume of Fluid) model used for free surfaces is 10 times faster than the previous model. An SST-SAS (Shear Stress Transport - Scale Adaptive Simulation) turbulence model is used for highly unsteady regions (e.g., separation zones) and where large-scale turbulence structures can be resolved without the time and grid-scale resolution issues inherent with other methods. Enhanced radiation heat transfer functionality includes radiation through optics, radiation from heated moving elements, and UV output. An improved artificial compressibility cavitation model aids with stable steady-state analyses, while an optional integrated optimization program using the Multi-Objective Genetic Algorithm enables optimization of multiple objectives.
