It is possible to import data from offset tables as given in an Excel spreadsheet. This example shows how to import the data as well as some hints on how to improve the quality to best fit shell modelling in GeniE.
The above lines can be created by importing the script file Read aft ship offset data from Excel.js. This file refers to the spread sheet aft_ship_offset.xls. Make sure you edit the path in the script file to match the location of your local copy of the spreadsheet.

When importing data based on this script, poly-curves will be defined. Close to knuckles the poly-curve will have a smooth shape,
hence it is necessary to manually insert knuckle points.

![]() |
Select the actual line, use the feature for divide, tick off for insert knuckle point at intersection. The position of the intersection point can be graphically selected. |

Knuckles have been inserted at the actual positions. Shells can now be inserted by using either skinning/lofting or curve net interpolation. In this case, curve net interpolation will give the best result. To use curve net interpolation it is necessary to define additional poly-curves. |

Additional poly-curves have been inserted and a finite element mesh created. |
