Sažetak
We present a frontal, quad based, Delaunay meshing algorithm adapted to the structures appearing in the ship structural analysis. The main contribution of the paper is the preprocessing algorithm which resolves the geometry of the object and divides it into plates where all of the intersections of the boundary edges are guaranteed to be the nodes of any mesh generated for such a geometry. The result of this preprocessing algorithm is a discrete description of the geometry which can be meshed by the automatic frontal mesher according to the requirements of the classification society. Further algorithmic solutions for the inclusion of openings in the plates are also presented. The resulting algorithm is wholly implemented in python, using open source gmsh system together with the opencad module. It is capable of generating as many as ten thousand quads per second. This is the efficiency comparable to the standard triangular mesh algorithms and is due to the efficient implementation of the Delaunay quad algorithm in gmsh. We present several models from the engineering praxis to illustrate our claims.
