International TechneGroup Limited (ITI) announces availability of the GHandI case study. GHandi was a successful, three-year UK government research initiative aimed at advancing geometry handling and integration (GHandI). New capabilities resulting from this project included enabling the automatic generation of a high quality mesh for computational fluid dynamics (CFD) simulation of the airflow around an aircraft.
One of the most fundamental properties affecting the aerodynamic performance of a body is its shape. Demands for improved performance and optimization of airframe shape simulation and analysis continue to increase. ITI’s CADfix team worked with GHandI program partners, including Airbus and MBDA, to develop new capabilities for extracting information from geometry and adapting for use elsewhere in the aerodynamic simulation process.
CADfix made three key contributions: advances in the unique CADfix medial object technology, automatic domain sub-division of the air close to the aircraft skin into connected partitions, and the development of a framework for integrating best in class meshing technologies and external components to orchestrate the creation of a high quality hybrid CFD mesh. The results demonstrate the potential for real application in future aerospace programs, and extend to improving geometry handling for internal airflow simulation in aero engines, hypersonic simulation of missiles, and other advanced aircraft simulations.
“The success of this initiative is meaningful for both the aerospace industry at large and for ITI,” stated Mark Gammon, Technical Director and CADfix Product Manager at ITI. “At this time, CADfix is the only tool that has proven success in implementing real world applications of the medial object, and has achieved exacting and robust results for generating high-quality mesh.”
