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) with being the number of nodes in the node group.
- The
Ascalex and
Fscaley are used to scale the abscissa and
ordinate.The actual load function value is calculated as following:
(2) Where, is the function of fct_IDT.
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.
