MODULES
Cradle CFD solution consists of the following products:
scFLOW
scFLOW is a next-generation CFD tool that uses unstructured mesh to accurately represent complicated geometry.
With a streamlined workflow, the Preprocessor aids users to generate high-quality polyhedral mesh elements and construct complicated models and the Solver ensures more stability and speed, scFLOW is capable of solving aerospace and automotive aerodynamics, performance of fans, pumps and other rotating equipment, design problems of electronic devices, multiphase phenomena, marine propeller cavitation, and varied problems effectively.
scSTREAM
scSTREAM is a general-purpose CFD tool that uses Cartesian or cylindrical structured mesh to enable easy mesh generation and high-speed simulations to be performed in a fraction of the time of other solutions.
Due to the meshing nature and analysis system that enables large-scale calculation, scSTREAM excels at processing extensive simulations, where users are required to solve engineering problems such as thermal problems of electronic devices and indoor environment, wind flow, and heat island phenomena.
scPOST
scPOST is a comprehensive and versatile data visualization software empowering users to instantly create a rich view of design performance. It has capability for a sharable light-weight format that supports virtual reality for a more immersive data visualization experience. In addition to fluid dynamics results, it also supports other simulation results from acoustics, structures and multibody dynamics all in one visualization solution.
HeatDesigner
HeatDesigner is a structured (Cartesian) mesh thermal fluid analysis software specially designed for electronics cooling thermal analysis. It uses core technology from Software Cradle’s scSTREAM general purpose structured mesh thermal-fluid software product.
HeatDesigner’s performance is optimized for applications that do not require precise reproduction of fine geometrical curvature to predict an accurate flow field. However, HeatDesigner is capable of accommodating meshes with over a hundred million elements enabling it to capture fine geometrical details. Like scSTREAM, the major advantages of HeatDesigner are fast calculations times and low memory consumption.
