Hexahedral Mesh Adaptation to Imprint Geometric Details: Application to CAD Models

Abstract

A novel algorithm is proposed to modify any unstructured hexahedral mesh in order to diminish the global time of numerical simulation processes, like optimization process and parametric studies. It consists in an imprinting algorithm that allows us to automatically add geometric details into an existing mesh. This addition is done using geometric projections, sheets (layers of hexahedral elements) insertions and combinatorial algorithms while preserving the hexahedral mesh structure as best as possible.
