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.F.2.2 [Theory of Computation]Nonnumerical Algorithms and ProblemsComputations on discrete structures
