*GMOVE

Data format:

A single line with 2 values followed by an arbitrary number of lines with 6 (or 3) values each :

IMOU DTMOU
Xi Yi Zi ( DXi DYi DZi )

Status : optional (dynamics)

Purpose :

To prescribe an arbitrary time dependent motion to a node

Details :

Parameter	Description
IMOU	identification number of the node with prescribed motion (must have been previously defined)
DTMOU	time step of the (equally spaced) time history table
Xi Yi Zi	The following lines are regularly spaced entries into the time history table : offsets with respect to the static equilibrium position of node IMOU at time ti = t0 + i * DTMOU(with i=1,n and 3<n<100)
DXi DYi DZi	The following lines are regularly spaced entries into the time history table : the 3 components of the absolute velocity of node IMOU at time ti.

Notes :

The user has the capability to provide only the table of co-ordinates Xi Yi Zi (other values left blanks). In that case the velocities are calculated by a program using a 3 points difference formula.
During dynamic simulation a cubic interpolation formula is applied to the data from the generated table.
