*RETENSTAT,FILE=Filename

Data format:

Three lines with the following parameters:

IGR INODE Kp Td Ti Lmin Lmax
DLLFileName
DLLProcName

Status :

Optional

Purpose :

To adjust the length of a mooring line in order to achieve a specified target tension

Restrictions :

A mooring line must have been created.

Details :

Parameter Description
filename.dat File where the tensioning scenario is specified. Two columns: Step and tension. Specify negative tension (for example -1), to indicate steps where the retensioner is OFF.
IGR The group of elements for which the length has to be adjusted
INODE The node at which the tension is to be computed, preferably corresponding to one end of the mooring line. If 0, compute the average tension in the group of elements IGR
T0 The target tension, in N, dummy if specified in a file
Kp Gain of the PID controller, in m/N
Td Derivative of the PID controller
Ti Integral of the PID controller
Lmin Minimum allowable line length
Lmax Optional : Maximum allowable line length
DLLFileName DLL file name
DLLProcName DLL procedure name
