Anisotropic metric-based mesh adaptation for unsteady CFD simulations involving moving geometries

PhD Position at Inria Saclay-Ile de France Title: Anisotropic Mesh Adaptation for RANS Simulations with Moving Geometries in Aeronautics

Subject: The aim of mesh adaptation is to generate automatically the best mesh to perform a specific numerical simulation [1]. It results in a powerful methodology that reduces significantly the size of the mesh required to reach the desired accuracy. Thus, it impacts favorably the simulation CPU time and memory requirement. Moreover, as the generated adapted mesh is in agreement with the physi...

Delaunay-Based Anisotropic Mesh Adaptation

Science and engineering applications often have anisotropic physics and therefore require anisotropic mesh adaptation. In common with previous researchers on this topic, we use metrics to specify the desired mesh. Where previous approaches are typically heuristic and sometimes require expensive optimization steps, our approach is an extension of isotropic Delaunay meshing methods and requires o...

Anisotropic Mesh Adaptation for Image Representation and Scaling

Triangular mesh has gained much interest in image representation and has been widely used in image processing. In this talk, a particular anisotropic mesh adaptation (AMA) method that has been successfully applied to solve PDEs will be introduced to image representation and image scaling. The AMA method is based on metric-specified mesh adaptation and finite element interpolation for Delaunay t...

Fully Anisotropic Goal-oriented Mesh Adaptation for Unsteady Flows

We present a new algorithm for combining a fully anisotropic goal-oriented mesh adaptation with the transient fixed point method for unsteady problems. The minimization of the error on a functional provides both the density and the anisotropy (stretching) of the optimal mesh. This method is used for specifying the mesh for a time subinterval from the state and the adjoint. The global transient ...
