  • Mesh regularization of ablating hypersonic vehicles

    Conference Proceeding  · 
    8th European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS 2022), Oslo, Norway.

    Authors: Claire Roche, Jérôme Breil, Marina Olazabal

    The ablation of a vehicle during atmospheric reentry leads to a degradation of its surface state. Ablated wall interacts with the boundary layer that develops around the object. The deformation can be seen as...

  • Mixed-Order Meshes through rp-adaptivity for Surface Fitting to Implicit Geometries

    Paper  · 
    SIAM International Meshing Roundtable Workshop 2024 (SIAM IMR 2024), Baltimore, Maryland, USA.

    Authors: Ketan Mittal, Veselin A. Dobrev, Patrick Knupp, Tzanio Kolev, Franck Ledoux, Claire Roche, Vladimir Z. Tomov

    Computational analysis with the finite element method requires geometrically accurate meshes. It is well known that high-order meshes can accurately capture curved surfaces with fewer degrees of...

  • Block-structured quad meshing for supersonic flow simulations

    Paper, Talk, Poster  · 
    SIAM International Meshing Roundtable Workshop 2023 (SIAM IMR 2023), Amsterdam, Netherlands.

    Authors: Claire Roche, Jérôme Breil, Thierry Hocquellet, Franck Ledoux

    Quad meshing is a very well-studied domain for many years. While the problem can be globally considered as solved, many approaches do not provide suitable inputs for Computational Fluid Dynamics (CFD) and in our case for...

  • Hexahedral Curved Block-Structured Mesh Generation for Atmospheric Re-Entry

    Thesis  · 
    Numerical simulation codes in fluid mechanics fall into two main classes. The two classes correspond to the type of mesh used for simulations, structured meshes and unstructured meshes. These two types of mesh each have advantages and disadvantages. Structured hexahedral meshes are equivalent to regular grids. In this case, numerous calculation optimizations are possible, for example it...
