Description: 
Algorithm 995: an efficient parallel anisotropic Delaunay mesh generator for twodimensional finite element analysis. A bottomup approach to parallel anisotropic mesh generation is presented by building a mesh generator starting from the basic operations of vertex insertion and Delaunay triangles. Applications focusing on highlift design or dynamic stall, or numerical methods and modeling test cases, still focus on twodimensional domains. This automated parallel mesh generation approach can generate highfidelity unstructured meshes with anisotropic boundary layers for use in the computational fluid dynamics field. The anisotropy requirement adds a level of complexity to a parallel meshing algorithm by making computation depend on the local alignment of elements, which in turn is dictated by geometric boundaries and the density functions – onedimensional spacing functions generated from an exponential distribution. This approach yields computational savings in mesh generation and flow solution through wellshaped anisotropic triangles instead of isotropic triangles. The validity of the meshes is shown through solution characteristic comparisons to verified reference solutions. A 79
