How can I apply a load on a partial area of a rotationally symmetric structural component only?


A free variable load allows you to apply a load on surfaces that can vary in height and perimeter.

Figure 01 shows a circular container that is only loaded by more than a half of the perimeter in the surface normal direction. To define a load varying along the perimeter, it is necessary to activate the "Varying" option" under "Along perimeter." Click the corresponding button to enter the factors for the load including the angles where they occur. Furthermore, you can define the rotation axis. The factor kα creates a reference to the load value p of the initial dialog box.

As an alternative, it is possible to split the surface into the corresponding surface components. Subsequently, you can apply a surface load to the relevant surface components.

The container shown in Figure 01 has been modeled with two partial surfaces in Figure 02. Thus, it is possible to apply the surface load to the container half that should be loaded.
