| Abstract | This paper considers issues associated with the construction and application of anisotropic meshes. Consideration is a first given to the meshing requirements associated with the transient solution of turbulent flow problems discretized using a stabilized finite element method. This study indicates the key importance of controlling the smoothness of mesh gradations on transient problems and demonstrates that in the presence of strongly anisotropic gradients the issue of what constitutes an unacceptably large dihedral angle does not follow the conventional thinking associated with meshes for problems with isotropic gradients. Progress on the development of mesh generation tools to provide the types of anisotropic meshes needed for these classes of problems and their application to a turbulent flow problem is also given. |
