 The Process
At Airbus France, shapes are first designed in ICEMSurf, imported from internal parametric generation software or directly from Catia v5 Digital Mockup. A "tetin" file is exported and mesh generation is performed using ICEM CFD Hexa, manually or using internal automated mesh generation tools based on the Can/Comak-Hexa facilities. Internal tools then enrich the mesh within the boundary layer and smooth it, while sticking to initial geometry using the ICEM CFD re-projection module. Various Navier-Stokes solvers may then be run, followed by proper post-processing to compute the drag and lift
coefficient. ICEM CFD Tetra is also used for aeroaccoustics and aerothermics computation purposes. Workflow is assisted and monitored through an internal scientific dedicated PDM, that ensure trace-ability of the complete process.
The Benefits
- An excellent link with ICEM SURF software allows the generated mesh to exactly match the initial CAD surface, which guarantees that Airbus are exactly computing the shape they designed.
- Excellent interactive meshing capability.
- A good integration within the Airbus industrial environment due to the efficient ICEM CFD support and key peripheral tools such as Can/Comak or stand-alone re-projection module.
- Acceptable batch capabilities.
