Procedure for Calibrating Holds

Create a new node under the Ship node. Select Grain Calibrations from the dialog. A new folder node is created.

Edit this new node, and select the compartments that are used to carry grain.

Set up data that will be common to all holds, for example, coaming height, cargo heights, filled hold options, , and select OK. This will generate a calculation node for each grain compartment.

Edit each grain compartment node to change any data that is specific to the compartment.

Select any 'tween deck from the list. (Only decks that span the compartment, will be listed.)

Check that the sections are properly defined, by exporting them as a Britfair (bri) file, and viewing/editing them in Digit. When the sections are deemed to be OK, they can be read back into Calc from the same dialog page.

Important:
It is very important to have properly defined sections, otherwise the results will be inaccurate.

Perform the calculations. This will generate grain calibration tables for each hold, and details of filled hold calculations, including diagrams showing the voids and level of the grain when shifted.
