An adaptive hybrid grid generation method for complex geometries

An adaptive hybrid mesh generation method is described to automatically provide spa-tial discretizations suitable for computational uid dynamics or other 2D solver applica-tions. This method employs a hierarchical grid generation technique to create a background mesh, an extrusion-type method for inserting boundary layers, and an unstructured tri-angulation to stitch between the boundary layers and background mesh. This method provides appropriate mesh resolution based on geometry segments from a file, and has the capability of adapting the background mesh based on a spacing field generated from solu-tion data or some other arbitrary source. By combining multiple approaches to the grid generation process, this method seeks to benefit from the strengths of each, while avoiding the weaknesses of each.
