Edge-Based Anisotropic Mesh Adaptation for CFD Applications

Anisotropic mesh adaptation for CFD computations

Unstructured mesh adaptation is now widely used in numerical simulations to improve the accuracy of the solutions as well as to capture the behavior of physical phenomena. In this paper, we propose a general purpose error estimate based on the interpolation error that produces an anisotropic metric map used to govern the mesh element creation. Application examples of CFD computations are given ...

3D transient fixed point mesh adaptation for time-dependent problems: Application to CFD simulations

This paper deals with the adaptation of unstructured meshes in three dimensions for transient problems with an emphasis on CFD simulations. The classical mesh adaptation scheme appears inappropriate when dealing with such problems. Hence, another approach based on a new mesh adaptation algorithm and a metric intersection in time procedure, suitable for capturing and track such phenomena, is pro...

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

Parallel anisotropic mesh adaptation with boundary layers for automated CFD simulations

This paper presents a set of parallel procedures for anisotropic mesh adaptation accounting for mixed element types used in boundary layer meshes, i.e., the presented procedures operate in parallel on distributed boundary layer meshes. The procedures accept anisotropic mesh metric field as an input for the desired mesh size field and apply local mesh modifications to adapt the mesh in order to ...

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...
