Body force
A body force acting on an element can be prescribed in any load case.
In the name.i2 file, a vector is first defined using a VV set:
VV set number T 6 V $Q_x$ $Q_y$ $Q_z$
and the set thus defined is then assigned to the selected elements:
AS load case number /$\dots$ /V set number E element number list /$\dots$
where $Q_x,Q_y,Q_z~[\text{N/m}^3]$ are the components of the force in the direction of the global axes.
Note
More than one assignment of body forces to a single element may occur within a single load case. Unlike other types of loading, in that case the force components are overwritten. Only the last assigned set therefore applies.
Note
The components of the vector can depend on the global coordinates $x,y,z$, using any of the available functional dependencies, see the Reference Manual.
