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.

Structured and Unstructured Mesh: The Differences

Software Cradle offers two different types of thermo-fluid analysis tools: scSTREAM and HeatDesigner with structured mesh, SC/Tetra and scFLOW with unstructured mesh.

Structured mesh is simple and easy to construct. Structured mesh is comprised of many small cuboids so it can only approximate curved or angled surfaces with stair-case patterns. It is most useful for applications where tiny details and surface curvature or angles do not have a strong effect on the overall results. Examples of applications for structured mesh include electronics cooling, HVAC, and architecture.

Unstructured mesh is created using tetrahedron, pentahedron, hexahedron, and/or polyhedron elements. Mesh is generated such that it fits along the ridge lines of the original geometry. As a result, unstructured mesh is used for applications where precise representation of geometry is crucial. Examples of applications for unstructured mesh include vehicle aerodynamics, fan blade designs, and flows inside ducts.

Analysis Procedure

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



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




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 features




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.
