Comments
 A displacement is imposed to node_ID_{N} from its initial position provided in /NODE, to its final position (X_{N}, Y_{N}, and Z_{N}).
 fct_ID is a scale factor on the imposed displacement, it should vary between 0 and 1.
 Abscissa scale factor,
Ascale is used to transform the function of time,
as:
(1) $$\mathrm{F}\left({t}^{\text{'}}\right)={\mathrm{f}}_{T}\left(\frac{t}{Ascale}\right)$$Where, ${\mathrm{f}}_{T}$ is the function of fct_ID_{T}.
 After T_{stop}, the nodes move freely.
 Initial node position N_{1} and final node position N_{2} can be defined as a spring N_{1}N_{2} with zero stiffness. The spring part_ID is optional and can be used to simplify the input since a preprocessor can easily generate springs between an initial position and a final one.
