PROPERTY LOADS GRAVITY [lname] [lnumb] part [opart] forc dof

          

This command is used to apply volume loads to a part.

lname = name of the loadcase, used at later references.

lnumb = loadcase number (integer, default=1).

part = part to be loaded, point, line, surface, body or set.

opart = optional part of next higher order from loaded part, which contains the elements to be loaded. Only required when there is ambiguity over which elements are to be loaded. See note 1.

forc = size of volume load.

dof = direction of gravity load 1 or X = global x 2 or Y = global y 3 or Z = global z

Notes:

1.

Ambiguity over which elements are loaded will only arise when the part that is loaded is attached to more than one other part, (for example where a load is applied to a line which is attached to two surfaces). Any ambiguity about which elements will be loaded can be resolved by specifying the part containing the elements to be loaded in the definition of the load.
The command is restricted to only allow certain combinations of parts i.e. point/line, line/surface and surface/body. In the case of sets, a similar relationship is required between the parts in the set.
If the load is to be applied to several of the parts sharing the loaded part, the command should be repeated for each part containing elements.
If the second (optional) part is not given then the load is applied to the part with the lower entity number.

Examples:

1.

PROPERTY LOADS GRAVITY LD1 B5 50. 1

Apply a gravity load of 50 to B5 along the x axis and call it LD1
