Use Frictional Contact between Beams and holes as the model that will be the easiest to converge.

After you have meshed and defined the contact, insert a Contact Tool under the Connections folder and Generate Initial Contact Status.  You need to see that the contact is Near Open or Closed. If it is Far Open, you will need to increase the Pinball Radius until it changes.

Under Analysis Settings, you turn on Auto Time Stepping.  Set the Inital and Minimum Substeps to 100 and the Maximum Substeps to 1000.
