Modelling and triangulation of geometrically complicated plane domains and some applications to fluid mechanics

An algorithm of modelling and triangulation of plain domains is presented. For the purpose of geometrical modelling of 2D domains apprio-priate topology is defined. B-spline curves represent the boundary. An algorithm of generation of graded grids on B-spline curves is worked out. The internal points are generated by using the advancing front technique. The triangulation is performed by means of the Delaunay advancing front method. Numerical examples present meshes over airfoils.
