Add a Body Load to domains for modeling general volumetric loads.
Select a Load type — Force per unit volume, Total force, or for 2D components,
Force per unit area, then enter values or expressions for the components in the matrix based on the selection and the space dimension.
If you are performing a linear buckling analysis with a combination of live and dead loads, select the Treat as dead load check box to indicate that the load contributions from this node are constant. The default is that a load is proportional to the load factor.
