Abstract

A method for creating a finite element model for stiffened shell structures is developed. The method is intended for complicated and non-homogeneous structures whose details determine the grid of the model, e.g., ship decks. It does not compete with the mesh generators that redefine an area according to some pattern.

The SFMESH-program uses points, lines and areas as geometric objects. With these objects, the element mesh is created. The mesh can be redefined afterwards without having to give the properties or boundary conditions again.

When creating the element mesh of a ship deck, only about 10% of the nodes need be defined by the user. No element topology has to be given. That is why the modelling is easy and time-saving. Moreover, there are less possibilities to make mistakes.
