Comments
 The direction of load must be right justified in the ten characters of field number 2.
 The grnd_ID input is
obligatory. The concentrated loads will only be applied to the nodal group. The force is applied
to each node individually, so:
(1) $$total\_force=\mathrm{F}\left(t\right)\cdot {N}_{node}$$with ${N}_{node}$ being the number of nodes in the node group.
 The
Ascale_{x} and
Fscale_{y} are used to scale the abscissa and
ordinate.The actual load function value is calculated as following:
(2) $$\mathrm{F}\left(t\right)=Fscal{e}_{y}\cdot {\mathrm{f}}_{T}\cdot \left(\frac{t}{Ascal{e}_{x}}\right)$$Where, ${\mathrm{f}}_{T}$ is the function of fct_ID_{T}.
The force is applied individually to each node of the nodal group. The total force is equivalent to the force value multiplied by the number of nodes.
