1.	A displacement is imposed to node_IDN from its initial position provided in /NODE, to its final position (XN, YN, and ZN).

2.	fct_ID is a scale factor on the imposed displacement, it should vary between 0 and 1.

3.	Abcissa scale factor, Ascale is used to transform the function of time, as follows:

4.	After Tstop, the nodes move freely.

5.	Initial node position N1 and final node position N2 can be defined as a spring N1N2 with zero stiffness. The spring part_ID is optional and can be used to simplify the input since a pre-processor can easily generate springs between an initial position and a final one.
