Boundary Load
Use a Boundary Load to apply tractions or pressure to boundaries.
Force
Select a Load typeForce per unit area (the default), Pressure, Total force, or for 2D components, Force per unit length. Then enter values or expressions for the components in the matrix based on the selection and the space dimension.
For Force per unit area, the body load as force per unit volume is then the value of F divided by the thickness.
For Total force, COMSOL Multiphysics then divides the total force by the area of the surfaces where the load is active.
For Pressure, it can represent a pressure or another external pressure. The pressure is positive when directed toward the solid.
After selecting a Load type, the Load list normally only contains User defined. When combining with another physics interface that can provide this type of load, it is also possible to choose a predefined load from this list.
