Current Activity A posteriori error estimation Anisotropic adaptive mesh  Mathematical Modeling of multiphase flows  Stabilized FEM for FluidStructure Interaction  Unstructured Mesh Application for CFD ► Anisotropic mesh adaptation: The developed approach is based on the definition of a metric field directly at the nodes of the mesh for a direct use in the meshing tools. First, the unit mesh metric is defined and well justified on a node basis, by using the statistical concept of length distribution tensors. Then, the interpolation error analysis is performed on the projected approximate scalar field along the edges. The error estimate is established on each edge whatever the dimension is. It enables to calculate a stretching factor providing a new edge length distribution, its associated tensor and the corresponding metric. The optimal stretching factor field is obtained by solving an optimization problem under the constraint of a fixed number of edges in the mesh.
► Dynamic parallel mesh adaptation procedure: . It is based on the definition of an anisotropic a posteriori error estimator, the search of the optimal mesh (metric) that minimizes the error estimator under the constraint of a given number of nodes and the use of the serial mesh generator (MTC) in a parallel context.
