Abstract

A three-dimensional mesh deformation scheme, based on frame analogy, is proposed in order to handle the large and irregular grid displacements typical of extended in-flight icing. The goal is to provide an approach that is robust enough to delay re-meshing or avoid it completely. The methodology is validated first in the case of large deformations typical of fluid-structure interaction problems, and is then assessed in aero-icing cases for its ability to preserve a good geometrical quality of the elements, especially at the fluid-solid interface.
