The effective seabed slope is no longer computed from the lay azimuth instead, if an explicit slope has not been set, it is computed from the positions of the line ends when the model is in reset state. It is now possible to explicitly specify the value of the effective seabed slope assumed in the computation of analytic catenary solutions. The TTurbineInstantaneousCalculationData structure has been extended to provide more fields that may be useful when writing turbine controllers, or wrapping existing turbine controllers. However, the simulation itself would not have been affected by this issue. The components, with respect to local axes, of vessel and winch connection loads, as well as line end loads, could also have been incorrect, if the object in question was attached to a turbine. Results for any shape connected to a turbine may have been incorrectly reported and the shape may have been drawn in the wrong position during the replay.This only affected lines with a non-zero contents flow rate. The Coriolis force arising from contents flow inside a line was being applied with the wrong sign.OrcaFlex is in use by over 260 clients, mainly in the offshore engineering business, with others in seismic, defence, ocean engineering, oceanographic research, aquaculture, compliant marine renewables and related fields.
