Thermo-fluid analysis software

Thermo-fluid analysis software is a simulation tool used for analyzing complex thermal/fluid phenomena. Software simulation enables predicting performance prior to hardware prototype. As a result, the tools can be used early in the planning state of product development to filter preliminary design concepts. Simulation can also be used to predict performance of products where it is difficult to make experimental measurements.
In addition, simulation software can be used to visualize invisible fluid flow and heat transfer. This results in increased engineering understanding while providing a vehicle for communicating this knowledge to non-experts.

scSTREAM and SC/Tetra

Cradle offers two different types of thermo-fluid analysis tools: scSTREAM (and HeatDesigner for electronics cooling) and SC/Tetra. scSTREAM and HeatDesigner use structured meshes while SC/Tetra uses an unstructured mesh.

A structured mesh is simple, easy to construct, and fast to solve. This mesh is comprised of many small cuboids so it can only approximate curved or angled surfaces. It is most useful for applications where tiny details and surface curvature or angles do not have a strong effect on the overall flow field. Examples of applications for structured mesh include electronics cooling, HVAC, and architecture.

An unstructured mesh contains more complex element shapes (tetrahedron, pentahedron, and hexahedron). These elements provide a flexible way to represent curved surfaces. As a result, SC/Tetra is used for applications where precise representation of the geometry is critical. Examples of unstructured mesh applications include fan blades and automotive aerodynamics.

Mesh generation

Analysis Procedure

There are three major steps in the workflow for obtaining simulation results: Preprocessor, Solver, and Postprocessor.

Pre-processor

Pre-processor

With Preprocessor, create or import analysis models, set analysis conditions, and generate mesh.

Solver 

Solver 

Flow/thermal calculations are performed using input data created in the Preprocessor. During the computation, calculation status can be monitored. The amount of time required for the computation depends on the size of the model (number of mesh elements), quality of the model, and hardware. A parallel Solver is available for reducing the computational time of large-scale models.

Solver

Post-processor 

Post-processor 

The Solver outputs field data for visualization using the Postprocessor. This permits examining flow, temperature, pressure, and other analysis results. Visualized results can be converted to images, animations and/or CradleViewer files for later use.
