Howbolt pretensions works in FEA?
First, the software divides a meshed body using the PSMESH command. Next, a pre- tension element effectively writes a constraint equation that relates the displacement of one cut boundary to the other. Within the simulation environment, the face selected is used as a cutting guide for the PSMESH command. This
means that you only need to select one clamshell face to define bolt load on an imported cylinder. The simulation tool
will then use the middle of the selected face for the mesh division and pretension element creation. Bolt preload direc-
tion is determined automatically. If you need more control over the preload application location, the bolt load can be scoped to a single body. You are then required to specify a coordinate system that defines the mesh slice plane and bolt load direction. This can be done through the default global or user-defined coordinate system. The XY-plane of the coordinate system defines the PSMESH slice plane, while the Z-axis defines the
direction of bolt preload. You don’t need to define the coordinate system “inside” the preloaded part.
