Setting up boundary conditions¶

Boundary or Body conditions are essential conditions for the most analyses. A boundary condition is imposed on the boundary of the geometry. For example, a displacement condition imposed on the face of the 3D solid geometry. A body condition is imposed on the entire body. For example, the rotational velocity imposed on the body.

Each analysis type has its boundary and body conditions. These boundary and body conditions will be described separately regarding structural, thermal, and electromagnetic analyses.

Note

The boundary condition here includes both boundary and body conditions.

Adding boundary and body conditions in WELSIM application is straightforward. The following describes the adding method and its behaviors.

• Adding new conditions from the Toolbar.
• Right clicking on the Study or its children objects and selecting the condition item from the context menu.

Scoping method¶

The scoping method supports the geometry selection, and you can select the target geometry entities and set to the properties. A voltage boundary condition scoping is illustrated in Figure below. You can select multiple geometry entities such as bodies, faces, edges, or vertices to a Geometry property, but all these entities must be the same type.

Tips in geometry selection¶

The following describes the tips in selecting geometries for boundary and body conditions:

• You can first select geometries and then apply to Geometry Selection property, or you can click the Geometry Selection property then select the geometries from the Graphics window.
• You can select multiple entities by pressing the Ctrl or Shift key.
• For the body conditions, you only select the volumes or bodies.
• For the boundary conditions, you only can select the faces or edges.
