SeaTrust-Holdan is a special purpose software package developed for the structural strength analysis of bulk carriers, double hull oil tankers, containers ships.
It consists of an automatic modeler, finite element solver and post processor.
This user-friendly system has been developed with Visual C++ based on MFC in Windows 95 and above, and can be operated in a personal computer with Pentium III processor, 128MB RAM and 500MB free disk space |

Creation of standard boundary condition and loadings based on KR guidelines
Graphic user interface based on the Windows 95 and above
Inclusion of finite element solver
Interface of MSC/NASTRAN

A ship structure is subdivided into primary members, secondary members and tertiary members. Primary members consist of side shell, bottom, inner bottom, deck, etc. Secondary members consist of web frames, transverse bulkheads, floor, etc.
Tertiary elements consist of web stiffeners, brackets, etc. A ship structure is idealized by using "top-down" approach which is |

While the resizing or modifying process, the program will automatically search for elements which will be influenced by the process and also adjusts them automatically. |
| |
|
| |
When some parts of the geometric data are changed, or when a user wants to generate FEM mesh from a geometrically similar ship, the user can save much time by resizing or modifying only some parts of the already established FEM mesh data. |
| |
|
| |
Topological information on frames and longitudinal stiffeners is included in basic ship data. Most elements are arranged by using this information.
Also, the shape and size of element is decided. Employing all information shown on ship drawings, even a novice in this field is able to make an easy arrangement of elements. |
