Joint boundary condition is a type of connection element that allows you to model the relative motion and interaction between two or more bodies in a structural analysis. Joint boundary condition can be used to simulate various types of joints, such as revolute, cylindrical, spherical, planar, slot, universal, and fixed joints. Joint boundary condition can also be used to apply loads and moments to the connected bodies. To use joint boundary condition in Ansys Static Structural, you need to follow these steps: In the Model tree, right-click Connections and select Insert > Joint. In the Details view, select the type of joint you want to create from the drop-down list. In the Geometry section, select the two or more bodies that you want to connect with the joint. You can also specify the location and orientation of the joint coordinate system (JCS) using the options available. In the Definition section, specify the degrees of freedom (DOF) that you want to allow or restrict for the
