*MVSURVEY

Data format:

A single line with 8 values:

INOD_FPF Lini Vx Vy Vz Rgyr AngGyr Tgyr

Status :

Optional (dynamics)

Purpose : To prescribe a survey type motion that means a constant speed motion combined with a change of direction to keep on new direction with the same velovity.

Details :

Parameter	Description
INOD_FPF	identification number of floater's node
(must have been previously defined)
LINI	Initial straight line motion
(Vx, Vy, Vz)	velocity vector components in the global frame
Rgyr	gyration radius to define the change of direction
AngGyr	Angle of gyration
Tgyr	(Optional) Beginning time for gyration

Example:

The figure below illustrates the following paramters of *MVSURVEY

*MVSURVEY
INOD 100 1.0 0.0 0.0 100 180 0

The initial velocity of 1m/s along X axis is kept constant over 100 meters, then a U-turn is ocnducted with a radius of 100m.

Finally, the floater is moving along -X at 1m/s.
