Reply To: Difference in edge to edge and surface to surface beam connection

Hi,

For defining the bolt pretension you can choose a vertex-edge or vertex-face type connection, to represent the force of the distribution on the edge or face due to bolt preload. The choice of connection type in ANSYS depends on the representation of the bolt (solid or beam) and the specific requirements of the simulation. It's not always limited to surface-to-surface connections, and edge selections can be used as part of the modeling process when appropriate.

Thanks,
