CFD Optimizes Light Jet in Study

By DE Editors

Using both Sculptor from Optimal Solutions Software, LLC (OSS; Provo, UT), its real-time CFD design deformation technology, and ANSYS, Inc.’s (Southpointe, PA) FLUENT software, the companies were able to assist in the CFD optimization of the wing and nacelle for Diamond Aircraft Industries’ D-Jet (London, Ontario, Canada).

The study culminated in a proprietary recommendation to Diamond that projects a significant improvement to wing/nacelle interference and stall characteristics.

Sculptor was used to deform the Baseline meshed geometry into new FLUENT case files for solving. The Baseline mesh was read into Sculptor, after which the engineer created an Arbitrary Shape Deformation (ASD) volume around the geometry that was to be deformed. The control points of the ASD were positioned and aligned to give the desired deformations. After the ASD volume was “frozen,” the engineer moved the control points, and the meshed geometry deformed accordingly.

Plus, optimization algorithms can be used to automatically move the control points to achieve automatic shape optimization. For this study, a total of five different ASD volumes were created to explore a variety of ways of deforming the baseline.
