2020 Software Release Feature Highlight: Importing FINE™/Open Grids and Starting CFD From a Previous CFD Run in pbPost™

Concepts NREC’s pbPost™ product was created to provide designers a turbomachinery-specific pre- and post-processing tool to link our flagship 3D design product, AxCent®, and our partner NUMECA International’s FINE™ CFD products.
There have long been challenges in using structured and unstructured grids together in a CFD analysis. This is most prevalent in turbomachinery design when including a volute in the full stage analysis. In many cases, the volute geometry was difficult to generate and grid automatically with a set of default values. This led to the need for repairing the grid directly within FINE™/Open. Until now, the designer would be left with the only option being to move forward in FINE™/Open with that specific design.
The new developments allow for the repaired unstructured volute grid to be imported back into the AxCent® software. This feature will allow a designer to complete more design studies on the rotor and stator design while holding that volute design constant, providing a more accurate simulation, a better understanding of the full stage performance, and the ability to drive critical design selections for all components to ensure design requirements are achieved.
Look for these, and other additional features when Concepts NREC releases the newest versions of our products on December 1, 2020.
