Assigning load condition sets

A load condition set is defined as explained in the previous section. The next step is to assign the set to a certain object. You can assign the currently active set to selected objects by clicking button of the dialog.

> Selecting objects to assign load conditions

The load condition sets may be applied to various objects. However, assignable object types are limited and determined by the type of load conditions, as indicated in the previous figures of "Editable text items" Only the selection tools of assignable objects are enabled and others are disabled, whenever the type of the current load set is altered.

> Assigning a load condition set to multiple objects

You can apply the current load condition set to more than one object. However, once the set is assigned, extra new load condition sets are automatically generated so that each of the selected objects is assigned with an independent set which has the same characteristics as that of the current set. So, you will find that the number of load condition sets is increased as much as the number of assigned objects minus one.

> Assigning multiple load condition sets to a single object

One object may be assigned with more than one load condition sets. But there is a possibility that you assign, by mistake, an identical load conditions to the same object more than once. In order to prevent such a trouble, VisualFEA does not allow assigning the same load condition to one object twice or more.

> Representation of load assignment

The assigned forces, except body forces, are represented by arrows indicating the point and the direction of their application. Body forces are indicated by x mark, instead of arrow, at the centroid of each element. The size of arrow can be adjusted using the slide bar of load drawing scale. The slide bar has relative scale of arrow size. The arrow size can be lengthened by moving the thumb of the bar to the right, and shortened by moving the thumb to the left.
