Abstract
A method for generating a specialized mesh in areas near the boundaries of a model, especially designed for use with boundary layers in fluid flow, is being used as part of a general-purpose automated quadrilateral and hexahedral mesh generation method. A structured mesh consisting of rows of thin elements is created in the specified region of the model. Control over the number, characteristics, and location of the elements are provided. Adjustments necessary to mesh entities affected by the special elements are dealt with internally. After the specialized regional meshing occurs, the remainder of the model is meshed using existing techniques. Meshes are currently being generated for both 2D and 3D problems.
