Although the subsequent dynamic simulation then starts from a non-equilibrium position, it does allow the simulation to proceed and the initial non-equilibrium errors will normally be dissipated during the build-up period of the simulation with a reasonably long build-up period. If statics fails, you can exclude some or all buoys (or, for 6D buoys, just the rotational degrees of freedom) from the static analysis this simplifies the calculation and should allow convergence. The static analysis is an iterative calculation and, for some complex systems, may fail to converge, especially if the given initial position is far from the equilibrium position. You may need to set this value to none if the model is statically indeterminate, for example a free-floating buoy, or if the static analysis fails to converge for some other reason. All is the usual setting, in which case the static analysis will include all the buoys along with the other objects in the model when it finds their static equilibrium positions.With 6D buoys, you can also choose whether the rotational degrees of freedom are included or excluded. Individually specified transfers control to the buoy data form, where each buoy may be included in, or excluded from, the static equilibrium calculation.X, Y, Z includes all buoys in the statics calculation, but excludes rotational degrees of freedom for 6D buoys.None means that OrcaFlex does not find the true static equilibrium position of any of the buoys in the model, but instead simply places them all at their initial starting positions given by the buoy data.Which buoys are included in the static analysis is controlled by setting the buoy degrees of freedom included in static analysis (on the general data form), together with individual settings on each buoy's data form: When a buoy is included OrcaFlex calculates the static equilibrium position of the buoy when it is excluded OrcaFlex simply leaves the buoy at the position specified by the user. Buoy degrees of freedom included in static analysisģD buoys and 6D buoys can either be included or excluded from the static analysis.
