*TENWIN

Data format:

A single line with 6 parameters, as follows:

IGR INO1 INO2 LENVAR NITER FACT

Status :

Optional

Purpose :

To adjust the global length of a group of elements to reach a target force

Details :

Parameter	Description
IGR	Group number which length will be adjusted (all element lengths are adjusted to get the chnage in total length)
INO1	Reference node where the reference force is computed (absolute value of the reaction force)
INO2	Second node where the follower force is computed (absolute value of the reaction force)
LENVAR	Variation in length of the whole group per iteration (m), signed quantity usually negative
NITER	Maximum number of iteration per step to reach the target value
FACT	Factor on the target value. The line total length is changed by LENVAR per iteration over a maximum of NITER iterations until load(INO1)
