Turn off line torsion in OrcaFlex

[buoy]

I am using the software OrcaFlex to model a mooring system. The twisting of the lines is not important to the dynamics, so I want the model to ignore torsion. The OrcaFlex manual isn't clear how to do this. Do I just set the line's torsional stiffness to zero?

Found out how: In the Line Data form for the mooring line (not the Line Type), there is a pull-down menu in the top center to turn torsion on or off.
