Field	Contents	SI Unit Example
cload_ID	Concentrated load block identifier (Integer, maximum 10 digits)
unit_ID	Optional unit identifier (Integer, maximum 10 digits)
cload_title	Concentrated load block title (Character, maximum 100 characters)
fct_IDT	Time function identifier (Integer)
Dir	Direction of load: X, Y, and Z for forces; XX, YY, and ZZ for moments (Text)
skew_ID	Skew identifier (Integer)
sens_ID	Sensor identifier ≠ 0: the concentrated load is applied after sensor activation (the time function is shifted in time). (Integer)
grnd_ID	Node group to which the concentrated loads are applied (Integer)
Ascalex	Abscissa scale factor Default = 1.0 (Real)
Fscaley	Ordinate scale factor Default = 1.0 (Real)

1.	The direction of load must be right justified in the ten characters of field number 2.

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:

total force = F(t) * number of nodes

3.	The Ascalex and Fscaley are used to scale the abscissa and ordinate.

The actual load function value is calculated as following:

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.
