Purpose: |
To support the user in the definition of the hull production block structure. The function estimates the weight and center of gravity of the steel contents within hull blocks, created by a fictive block division of the hull model. The fictive block division is achieved by dividing the complete hull model by a number of axis-aligned boxes given within a comma-separated input file. The input file can have the following three different formats:
|
|
In all the three alternatives, the first row of the file must be a comma-separated headline, from which the input format can be decided, for example, if file format alternative number 3 is used, then the headline shall consist of only one word without any commas. The calculation result is presented by adding the calculated values to the given comma-separated file at the end of each row. The function can be used iteratively, making changes to the box information and re-running using the same file. If the file format alternative 2 is used and the result from this calculation is accepted, production blocks can be generated using the same file as input. |
|
|
The calculations are done by intersecting the hull model by the given boxes and then calculating the weight and centre of gravity of the hull items in each box. A fixed density of 7.84E-6 is used. The actual material definition of the hull is not considered. The intention of the function is support in the definition of a production block structure and design blocks are therefore not considered. |
