For the particular body loads that you can apply, list or delete with any of the commands listed in
Table 2.8: Commands for Applying Body Loads (p. 40), see the Command Reference

Below are examples of some of the GUI paths to use for applying body loads:

GUI:

Main Menu> Preprocessor> Loads> Define Loads> Apply> load type> On Nodes

Utility Menu> List> Loads> Body> On Picked Elems

Main Menu> Solution> Define Loads> Apply> load type> On Keypoints

Utility Menu> List> Loads> Body> On Picked Lines

Main Menu> Solution> Define Loads> Apply> load type> On Volumes

See the Command Reference for descriptions of the commands listed in Table 2.8: Commands for Applying
Body Loads (p. 40).

Note

Body loads you specify on nodes are independent of those specified on elements. For a

given element, the program determines which loads to use as follows:

• It checks to see if you specified elements for body loads.


• If not, it uses body loads specified for nodes.


• If no body loads exist for elements or nodes, the body loads specified via the BFUNIF command take effect.

2.5.8.1. Specifying Body Loads for Elements

The BFE command specifies body loads on an element-by-element basis. However, you can specify
body loads at several locations on an element, requiring multiple load values for one element. The
locations used vary from element type to element type, as shown in the examples that follow. The de-
faults (for locations where no body loads are specified) also vary from element type to element type.
Therefore, be sure to refer to the element documentation online or in the Element Reference before you
specify body loads on elements.

• For 2-D and 3-D solid elements (PLANEnnn and SOLIDnnn), the locations for body loads are usually
  the corner nodes.
