Research Project: Generation of valid high-order curved meshes
Advisor: Laurent Busé
Institution: INRIA, France

Curvilinear meshes offer more flexibility and better accuracy compared to (more common) simplicial meshes. Their generation is an active area of research: it requires to conform curved elements to a given boundary geometry, enforce a smooth and non-degenerate Jacobian everywhere, and keep the mesh as coarse as possible. Several attempts exist to accommodate these three properties. Building on a new variational approach, called Curved Optimal Delaunay Triangulation (CODT), that has been recently introduced to generate such meshes, the main objective of this project will be to develop new methods in order to generate a valid high-order curved meshes made of Bézier triangles. For that purpose, algebraic and subdivision techniques will be investigated for the detection of self-intersection and surface/surface intersection loci, for the preservation of sharp features and for controlling regularity.

Expected Results: a reliable and robust algorithm to detect intersection and self-intersection of low degree Bézier triangles, and an improved CODT method preserving the topology and sharp features of the input data.

The project will take place at INRIA Sophia-Antipolis. The PhD will be awarded by the University of Nice.

Secondments are planned at Universitat de Barcelona (Barcelona, Spain), and at industrial partner RISC-SW (Linz, Austria).
