Direct calculations of tank data

Posted on July 14, 2020

Until now, the tank data from the weight list of a loading condition were interpolated on a pre-calculated tank table. This required tank tables to be calculated in the Layout module. In this implementation, the accuracy of the interpolated data was dependent on the step size of the computation of the table.

Recently, in PIAS a setting has been added which commands the tank data to be computed directly, exactly for the given weight or filling percentage. In this mode, the computational results are for actual level, trim, heel and tank geometry, and may hence deviate from (previously) interpolated results, which could be subject to interpolation inaccuracies.

With this setting, the tank table is calculated on demand, so tables are no longer stored with the compartments in Layout. After defining a tank, it can be used in Loading immediately.
