| Popis: | In this paper we benchmark the performance of three algorithms for generating quad dominated surface meshes of the geometric models in ship structural analysis. We compare algorithms based on the combinatorial approach of packing the surfaces with parallelograms and those algorithms which are based on the variants of the Delaunay advancing front approaches. The meshing in ships structural analysis is specific in that the restrictions on the algorithm are defined by the rules of the ship classification societies which contain linear restrictions on the geometry. Linear restrictions are directly at odds with the principles of the Delaunay advancing front approaches. We present a specific quality indicator for assessing the quality of such meshes and compare three available algorithms in Gmsh. Finally, we assess the performance of our preconditioning strategy for these algorithms and argue for its suitability for the task. |
