![]() This is used to define the sense of the line. We recommend that the full statics option is selected, as this is the only line statics option in OrcaFlex that includes the effects of torsion. If torsion is included for a line, the static analysis should also include the effects of torsion – otherwise the simulation will start from a position that is not in torsional equilibrium and an unstable simulation may result. To check visually that you have the orientation you expect, you can draw the node axes. The gamma angle determines the torsional position of the line end. This is done by setting the gamma angle of the end connections on the line data form. If torsion is included for a line, you must define the torsional orientation at each end of the line. The node axes are drawn using the node pen, defined on the line data form. ![]() ![]() These axes show you how the line is behaving torsionally. To see the line orientation on the 3D view, you can tell OrcaFlex to draw the node axes at each node. If torsion is included then the line type torsional properties must be specified. Torsional effects can be included or ignored, for each line in the model. ![]()
