SC/Tetra V7 CFD software has been released and offers improved operability and new physical models with special appeal to designers of rotating equipment, HVAC engineers, and anyone modeling complex geometries. 

Improved Physical Models for Simulating Rotating Equipment

Modeling rotating equipment has always been one of SC/Tetra's major strengths.  V7 continues to enhance these capabilities:

o       Multi-moving function.  Two or more rotating or moving conditions can be applied to a single object.  An agitator can be rotating about an arm which is also rotating around a different axis

o       Freestream driven rotation or movement.  Simulations can be performed of an object driven by freestream forces.  Windmills and passive valves are examples.

o      Overset mesh.  Flow computations use overlapping meshes which eliminates mesh stretching and shrinking when the mesh moves.  This  is ideal for modeling intersecting boundaries such as when gear teeth engage.  This  can also be used to model a moving object that contacts a wall and closes off the flow path such as a ball or intake valve.

If the HVAC Air Flow and Temperatures are Right, How Come the Customer isn't Comfortable?

To meet the demands of the HVAC engineering community, SC/Tetra V7 contains a human body thermal regulation model that calculates body skin temperatures, heat transfer to and from the surrounding environment (including conduction where the body contacts its physical surroundings), and moisture evaporation.  The user can tailor the model for specific individual characteristics by specifying the subject's age, gender, % body fat, and metabolic rate.  Human body thermal models are being offered in specialized heat transfer software; however, SC/Tetra V7 integrates the human regulation model directly into the CFD software so coupling between the body and the thermal/fluid environment is seamlessly achieved.

Fully Integrated Wrapping Functions Slash Days Off  Time Required for Modeling Complex Geometries

SC/Tetra V7's fully integrated wrapping function
automatically eliminates minute physical detail in the model geometry that are not important to the CFD solution.  Wrapping also eliminates overlapping surfaces that are nuisance artifacts of the CAD process.  Manually performing these tedious processes usually takes days.  Using V7's wrapping function, a complete surface mesh for highly complex geometries can be generated in minutes.  Integrated wrapping augments SC/Tetra's already powerful grid generation, and mesh repair and diagnostics capabilties that rival 3rd party grid generation software.  

Post-processing large CFD models should not look like morphing

Manipulating large CFD models during post-processing is often like watching an image morph because response is so slow.   SC/Tetra V7 brings instantaneous response back to post-processing by implementing a  high speed, memory efficient iFLD data format.  A 25 million cell model of a Formula I race car requiring 8GB of computer memory is reduced to 615MB of memory using iFLD format.  The new iFLD format improves graphics performance for both 32 and 64 bit computer architectures.
