MAILLE: A Meshing Tool, Based on Anamorphic Stretching of a Pre-Meshed Cube and Dedicated to Car Interior Modelization

The heat transfer through different layers of materials, natural and forced convection, radiation, and external conditions are important in evaluating the comfort in a passenger car environment.

The solvers commonly utilised, do not take all these coupled criteria into account and they require a laborious meshing step (80% of CAE's activities) which is not compatible with the development cycle.

An anamorphic stretch of a pre-meshed cube to the targeted geometry allows a reduction of time by a factor of 10 or more.

This paper describes both the tool, its related methodology and offers a comparison with classical meshing for a large set of topologies. This work uses some experimental and theorical results from the CLIMHAB project¹.
