For Total force, COMSOL Multiphysics divides the total force by the number of points where the load is active. Then the force is applied in the same way as for Force per point.

For Resultant, enter the Force and Moment with respect to a point. Select the Application point defined using — Centroid, Point, or Coordinates. For Centroid, the coordinates of the application point is the centroid of the selected points. For Point, select a geometrical point in the section Application Point. For Coordinates, enter the Application point coordinates xa.

When using the Resultant option, the following should be observed
|
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.
