摘要： A computer-implemented method for generating a computer model of a composite component includes offsetting a projected ply curved surface outwardly along a base surface to define an offset ply curved surface. The method also includes defining a ply drop region of the base surface, the ply drop region includes another area of the base surface that is exterior to a ply curved surface and interior to an offset ply curved surface. A surface mesh is generated based on the ply drop region and the ply curved surface. The method includes generating a node data comprising a plurality of node points relative to the ply drop regions. Moreover, the method includes applying a curved function to the plurality of node points to facilitate forming a smoothed node data across the ply drop region. A ply mesh is generated using the smoothed node data and the surface mesh.
