Select WRC 107 to define local forces and moments according to WRC 107 conventions. Select Global to define local forces and moments in global coordinates. The selected convention is applied to the vessel, the nozzle, and the loads.
For both conventions, enter values for Direction Cosines, Sustained Loads, Expansion Loads, and Occasional Loads. The software compares stresses intensities to allowable stresses based on the value for Vessel Material selected on the Vessel tab. When you switch convention systems, the software converts loads from one system to the other.
