GGU-ELASTIC: "Area loads" menu item
The dimension of area loads is e.g. kN/m²/m = kN/m³.
You can assign certain elements area loads in x and y direction.

Area loads act in the representation plane. Own-weight loads are e.g. area loads in y-direction. The own-weight of triangular elements can, however, be defined more easily via the definition of "" in the menu item "System/Material properties".
Area loads in x-direction are rather rare in soil mechanics. An area load in x-direction would be e.g. a centrifugal force.

If you select the "Add area load" check box, the value entered will be added to any area loads already present.
