Design Case 2 Density Field Top And Associated Anisotropic Adapted Note that the mesh adaptation procedure starts after the metric field is set on the initial mesh. except for the first mesh adaptation step, the mesh generated in the previous step is used for defining the metric field in the current step. during the mesh adaptation process, the metric field is also updated accordingly as the mesh changes. (a) anisotropic, adapted unstructured mesh (maximum element aspect ratio = 10, number of triangle vertices = 16,699), from the simulation shown in figure 4; (b, c) high resolution images of specific mesh sections, illustrating anisotropic elements within the thermal boundary layer; (d) a near isotropic unstructured mesh (maximum element aspect ratio = 1, number of triangle vertices = 94,133. In the context of a mesh convergence analysis this adaptation loop (step 1) has to be repeated for several increasing mesh complexities {c j} j = 1 j m a x with j m a x the number of considered complexities, i.e., the total number of meshes for the mesh convergence analysis. an efficient strategy consists in converging the couple mesh solution for a given complexity and reuse the final mesh. Solutions of such flows. the adaptive technique is general and can be ap­ plied to a wide range of finite element, finite volume or finite difference problems. in the following sections, the anisotropic adaptation criterion is first presented, then the adaptive strategy and its implementation for triangu­ lar and quadrilateral meshes is shown.

Initial mesh (a) and natural mesh (b) with 4 element layers (193 nodes) in 2d. with several notations, the local anisotropy of a given geometry can be defined ( section 3.1 ). then, an approximation of the natural metric can be computed ( 3.2 successive neighborhoods , 3.3 elliptic interpolation , 3.4 the appropriate order ). Improvements to a local modification based anisotropic mesh adaptation procedure are presented. the first improvement focuses on control of the local operations that modify the mesh to satisfy the given anisotropic mesh metric field. the second is the parallelization of the mesh modification procedures to support effective parallel adaptive analysis. the resulting procedures are demonstrated.
