Body Load to domains (to model gravity effects, for example).

Boundary Load to boundaries (a pressure acting on a boundary, for example).

•
|
Edge Load to edges in 3D (a force distributed along an edge, for example).
|

|
Point Load to points (concentrated forces at points).

For 2D axisymmetric components, COMSOL Multiphysics takes the axial symmetry boundaries (at r = 0) into account and automatically adds an Axial Symmetry node to the component that is valid on the axial symmetry boundaries only.
