BLSURF - Mesh Generator for Composite Parametric Surfaces. Three-dimensional surface meshing is of utmost importance in many numerical applications including the finite element method. It is a necessary step when one wants to construct the mesh of a solid object. A wide range of surfaces can be defined by means of composite parametric patches. Most of the surfaces are approximated by polynomial or rational parametric patches as is the case for most CAD-CAM modelers. The method implemented in the BLSURF software is suitable for generating a mesh which conforms to given constraints (prescribed sizes of the elements in the vicinity of points of the surfaces) and closely approximates the geometry of the surface. It consists of meshing a 2D parametric domain, and a surface mesh is obtained when this is mapped to the 3D space. By discretizing first the interface curves which represent the common boundary of the patches, it has been adapted to surfaces made up of several parametric patches. ...
