Abstract
An algorithm of graded meshes generation and adaptation in 2-D case is presented. B-spline curves are used to represent the boundary. An algorithm of generation of graded grids on B-spline curves is worked out. Internal points are generated by using the advancing front technique. The adaptation is performed by remeshing based on modffication mesh density function, which defines the size of generated elements. On example problem numerical results of adaptation are shown.
