ANSYS FLUENT Fluent Inc. the worldwide leader in computational fluid dynamics, CFD, announces the release of GAMBIT 2.2, a major upgrade to Fluentís geometry and mesh generation software. This version provides several new key functionality benefits to CFD users:
  • Improved Geometry Construction and Clean-up Tools
  • State-of-the art Meshing Size Functions
  • Improved Quad paving and Boundary Layer Meshing

GAMBIT 2.1ís semi-automatic Cleanup tools have been enhanced now in v2.2. Fully automatic cleanup options are available for the most critical bottlenecks like slivers, short edges and sharp angles. A new "Cleanup Duplicate" geometry functionality has been added helping to provide full Cleanup toolkit for rapid geometry conditioning.

New smoothing and enhanced "Healing" operations also continue to produce higher quality geometries. Holes can easily be covered with an extended wire frame operation and flow domains can be created using the new, fully automatic, multi-volume stitch algorithm.

GAMBIT 2.2ís Meshing Size Function feature has been praised by many beta testers as the leading mesh distributing technology on the CFD market. With a drastic speed increase and a new exiting "Meshed" Size Function, Gambit 2.2 provides a high quality mesh on virtually any geometry model. In addition, several quality and flexibility enhancements have been added to the Boundary Layer mesher and the codeís unique Quad Paver. Antonio Bennardo, an engineer from EniTecnologie in Italy comments "I was impressed by the speed-up of the Size Function in Gambit 2.2. Besides, the unstructured quad mesher has been improved resulting in a mesh with better size transition and quality."

Erling Eklund, Fluentís GAMBIT Product Manager notes that, "Besides our standard QA testing, Gambit 2.2ís file import, healing, cleanup and size function capabilities has been thoroughly tested on an additional 40-50 challenging industrial geometries. Our aim is not only to improve efficiency in CFD preprocessing but also to provide higher quality products."
