This article is edited from a paper presented at a conference hosted by ANSYS. ANSYS designs and develops simulation software and technologies that optimise product development processes for designers and engineers in computer-aided engineering by delivering functionality including advanced analysis, meshing, optimisation, multiphysics and multibody dynamics.

During the early stages of the design process of a new aircraft there is a need to verify the influence of a large number of geometric parameters on its overall configuration. High fidelity engineering analyses at this stage are often extremely time consuming due to the frequently changing configuration, under a high level of interdependence among the disciplines. Moreover, the processes involved are hardly automated due to difficulties in the interface between computer-aided design (CAD) and computer-aided engineering (CAE) tools.

In order to achieve efficient design cycles in that context, an integrated working environment is desired, where geometrical changes can be easily introduced and computational meshes automatically generated, providing support for the engineering analysis. This text briefly describes a tool that accomplishes those goals thro....
