Computational Fluid Dynamics
Computational Fluid Dynamics (CFD), is a simulation tool used for analyzing complex thermal and fluid phenomena. It is instrumental in maintaining the quality and safety of many products we use on a day to day basis, such as an automobile or even the house we live in. CFD software is indispensable for "Front-loading" product development to ensure the best product concepts are identified early in the design process. Design quality will be improved during the conceptual design phase by conducting basic studies of fluid and thermal phenomena that directly affect product performance.
Visualizing the complicated movements of a gas or liquid flow can be quite convoluted. By implementing simulation software, Cradle CFD, into the workflow, analyzing these movements is easier than ever. It enables the user to predict the performance of their products before physical testing. This results in a more optimized design early in the product development cycle. In some cases, simulation can even replace the need for physical testing, altogether. Utilizing Cradle CFD will provide engineers with the understanding of these type of movements and an easy to use tool that anyone could implement.
Cradle CFD strength lies in its coupling capacity with other simulations tools, such as mechanical and structural software. The reinforced co-simulation capability with MSC Software products, such as Marc, Nastran, Adams, and Actran, it is possible to represent more accurate, realistic phenomena in simulations, allowing users to take more pragmatic approach for assessing design performance and potential risks.

Import native data from major 3D CAD software as well as most generalized intermediate data formats (Parasolid XT, STEP, and others). Cradle CFD can import 10+ types of CAD native data and 15+ types of intermediate data formats.
From the CAD data to analysis mesh data, the required operations are grossly simplified. The conservation of assembly information and the settings of conditions on the parts bring the sense of continuity from the CAD operations and reduce the operational burden of the users.
Structured and Unstructured mesh
Cradle CFD generates analysis models in two ways; scSTREAM uses structured mesh, and scFLOW generates unstructured mesh, and each has its own benefits. Structured mesh is easy to construct, characterized by high speed processing capability, and best suited to evaluate phenomena where detailed geometry representation is not required, such as thermal dissipation design of electronic devices, wind flow evaluation around buildings, and air-conditioning performance. Unstructured mesh enables highly accurate geometry representation, and excels in phenomena where precise geometry generation is crucial, such as evaluation of vehicle aerodynamic performance and assessment of fan blade geometry.
Parallel computing makes possible solving existing models faster, conducting more analyses, and/or solving more detailed models with a greater number of mesh elements.
